  1. Very excited for the Mig-19. The only thing I'm concerned about is how well they manage to implement the Spin Scan radar. Old school pulsed analog radars are hit or miss in DCS. The Viggen and Mig-21 radars were done well. But the F-5E radar was very poorly done. MIG-19 Spin Scan radar
  2. Depends on which ALR-67 we get (ALR-67v2, ALR-67v2(ECP-510), ALR-67v3) But compared to the ALR-56C (TEWS on F-15C) the ALR-67v2 (the most basic one we could get) has some capabilities the TEWS doesn't. -Low band direction finding -Varied Audio tones (dependent on emitter type, lock vs scan, emitter range) -Threat rings instead of relative range -The ALR-67 works and shares data with the radar, datalink, countermeasure dispenser, jammer, HARM. -ALR-67 emitters can be displayed almost everywhere. (Azimuth scope, HUD, JHMCS, SA page, EW Page. it may also go to the A2A radar page? not 100% on that though) -It also incorporates Inertial guidance system (INS) stabilization for accurate display in high g manoeuvres and during high roll maneuvers. Overal the ALR-67 is more modern and provides more information, more audio cues, and works with more systems than the -56C.

    jhmcs

    It does display RWR info.. Both of the above were recorded from the JHMCS helmet recorder hence why they're grey scale. Below is what the actual JHMCS looks like from the pilots eye.
  4. I too am curious with the order they wish to release capabilities.
  5. thanks! So, can the ATFLIR be displayed in black/white on the MPCD?
  6. Yes.. But it does more. The F-16 HSD page doesn't show RWR contacts, who you're jamming, HARM designations, etc. Does anyone know what colors the DDIs can emit? Obviously green, but after watching a number of F/A-18C videos it looks like it can emit red as well. Though its hard to tell because the raster of the CRTs isn't synchronized with the shutter of the digital cameras recording it. Which makes me think it can render green, red and a mix of the two, yellow. There is also a "color" option in the data sub-menu of the Radar attack page.
  7. SA page shows everything. RWR, radar, link-16, designated ground targets, way-points, pre-loaded threats, etc.
  8. Ground radar API was created. But it wont be integrated into the DCS AN/APG-73 radar until after the early access release of the DCS: F/A-18C. Right now they are working on the A2A portion of the APG-73 RWS, STT, and ACM modes which will be available with the release of the jet in EA.
  9. I would love to buy a cougar throttle.. Really like the thumb TDC, Antenna elevation, etc. I cant seem to find any available
  10. I'm hoping the delay from TM has to do with a new F-18 throttle
  11. very disappointing to hear I wouldn't ever fly as a RIO if the cat was restricted from using the weapon system it was designed for.
  12. REDFOR fanboys will be crying all over the forums when I'm done with them.. I'll just turn on my AWG-9 and they'll start burning energy turning. I'll wait till about 30 miles to make my first shot, just as they're about to setup their first launch. At that point they'll assume that 1. I dont see them (i will) 2. That now is the time to commit At 30 miles my AIM-54 will run them into the dirt.
  13. HUD + FLIR simulation footage? EDIT: watched their other video and it looks like these guys got some time to play with the USN F/A-18C simulator. So this is what the Navy's simulator displays.. At least back in 2002. Also, some HMD footage. (at the 35:34 mark)
  14. We've found more ALR-67v2 tones! Hope it helps https://forums.eagle.ru/showpost.php?p=3347570&postcount=9
  15. Looks great but I'd like to see -one of the two sliders replaced with the two forward buttons and extended (zoom slider). -An analog slew on the throttle (or perhaps a new grip that can support one)
  16. -Move the default view as far back as possible. -Set max FOV to 104 (or reduce the saturation in the zoom axis to something tolerable) EDIT: 104 is what I use with a 16:9 monitor. So play with your settings to see what you like. It may be easier to adjust the saturation of the zoom axis because you dont have to leave the game and go into LUA files. Also, I've seen other flights sims where the edge distortion isn't nearly as bad at the same FOV.. I understand the logic presented here as to why this occurs, but never the less the effect isn't noticeable as much with the other sim.. IDK why..
  17. I wasn't stating that the manual mentioned anything about CW. I was countering Alfa's post. I think he mis-interpreted the text he posted. I think all it was saying is that the illuminator is integrated into the primary radar rather than having a separate illumination antenna and transmitter. My example, the MIG-25, has its illuminator antennas at the wing tips. label 34 and 50 in the below link http://aviazioneaereimilitari.altervista.org/blog/wp-content/uploads/2013/05/MIG-25.jpg I am not certain if CW is there or not. But I have yet to see anything stating that it uses HPRF illumination. I think were on different pages here. I'm not saying CW waveforms were used for tracking or detection. I saying that CW waveforms are perfectly fine for illumination. The primary downside being that its obvious to the target that they are being launched on since 'normal' search and tracking waveforms are not CW. IMO the push for HPRF illumination was its ability to hide the fact that you are illuminating the target. Though I'm sure other factors like transmitter functionality and duty cycle limits were also factors.
  18. CW waveforms have excellent Doppler resolution, even better than HPRF. The problem with look down is targets hiding in the doppler notch, and neither HPRF or CW waveforms can prevent that. I think you've mis-interpreted that paragraph. The N001 and N019 were some of the first russian airborne radars to integrate the illuminator into the primary radar. Mig-25 and earlier jets had a entirely separate antenna and transmitter from the main tracking radar for SARH illumination. From an engineering perspective, this is something worth bragging about as its certainly highlights the complexity of the system. Also, it mentions "illumination is carried out within the time diagram of the radar". IDK if this was completely translated correctly, but I take this to mean that the illuminator time shares the antenna and transmitter with the normal tracking waveform. Indicating two separate waveforms. This seems like something that would be necessary if the illuminator was CW. If the illuminator used a HPRF, then its not likely to need to time share as the tracking waveform would also be the illuminating. Its important to note that IF it does use a CW waveform for illumination the radar would not be able to track the target (because there is only one antenna and radars of this design/era cannot transmit and receive at the same time. So switching back and forth between the tracking waveform and the illuminator (time sharing) would be necessary to continue to point the illuminator at the target. Yes, IMO flood mode should just look like HPRF STT. However, someone could argue that HPRF illumination looks different than regular HPRF tracking. And that would be an interesting debate that wouldn't ever be solved. However, there is one thing we can guarantee. Launching a missile in FLOOD mode shouldn't change the FLOOD waveform what-so-ever. Thus there can only be two options. 1. FLOOD mode gives STT (lock on) warning. or 2. FLOOD mode gives launch warning (even if no missile has actually been launched). Considering how powerful #2 would be in game, I'm willing to bet people would be content with #1. Again, I think #1 is the more likely scenario.
  19. Would very much like to see your sources
  20. You sure about that? If those missiles dont use CW SARH why do even the newer flanker radars, BARS and IRBIS, have CW illumination? http://www.ausairpower.net/APA-Flanker-Radars.html
  21. 1. LPRF systems can use CHIRP. (linear RF modulation during the pulse) Perhaps you are confusing CHIRP with Frequency Modulated ranging (FMR)? FMR offers poor range accuracy and degrades coherent pulse integration. FMR is mainly used with HPRF since range is ambiguous. It may also be used with any waveform (LPRF, MPRF) for electronic protection/anti-jamming purposes. 2. Doppler is ambiguous with low prf. Doppler processing cannot be achieved by an airborne system with a low PRF. However, if they have a coherent waveform they can perform MTI. Which is to say they can filter out the ground clutter but they cannot determine a targets velocity. If you'd like to know more about doppler ambiguity read the links below http://www.radartutorial.eu/01.basics/Doppler%20Dilemma.en.html https://en.wikipedia.org/wiki/Frequency_ambiguity_resolution LPRF waveforms are not restricted to small or large pulse widths. older LPRF tracking radars had small pulse widths for range resolution. Modern LPRF radars likely use longer pulse durations with pulse compression because it gives them good range resolution AND more energy on target. 1. if you are talking about a CHIRP, then to answer your question doppler isn't derived from a single pulse. Doppler is derived from a series of pulses. The shorter the FFT the more ambiguous the frequency spectrum. Remember, frequency is the measure of cycles per second. Running a FFT on a single pulse would smear the doppler spectrum. Also, there would be aliasing due to the de-synchronization of the PRF to the Doppler frequency of the target. Also, there are a large number of doppler bins if you're worried about a doppler shift affecting the pulse compression This again may help https://en.wikipedia.org/wiki/Frequency_ambiguity_resolution 2. if you are again referring to FMR, then yes range errors could occur from the targets doppler IF you were using a saw-tooth waveform. However, a triangular waveform allows you to determine the range and doppler of a target by sweeping the frequency (pulse to pulse, not within one pulse) both directions.

  22. Thanks for the response Zeus!
  23. Thanks! Do you know if they plan on making the EW page or adding RWR indication to the HUD?
  24. is there no lock tone?
  25. Modulation occurs during the transmission of the pulse. Imagine having a flashlight that starts it's 'flash' as red light but gradually slides to green and then to blue... Every time you hit the flashlight button it starts red and slides through spectrum to blue.
