GIGA_HORSE Posted December 18, 2019 Share Posted December 18, 2019 (edited) No matter how I tried, in every radar mode, nothing happens. Interestingly though the SD-10 sees helicopters and is able to lock on after release if I am close enough Edited March 11, 2020 by uboats Link to comment Share on other sites More sharing options...

DackSter94 Posted December 19, 2019 Share Posted December 19, 2019 Seems that notch isn't implemented as on other aircraft(right/wrong implementation?) - which i absolutely love btw, none of that hiding bu****** :D. So instead of having target flight direction in mind it's just based purely on speed. It seems to be around 120 knots, if anything flyes above it it can be spoted, even in the notch. If it's below it will not get picked up, even against the sky LOOK MA, NO HOOK Link to comment Share on other sites More sharing options...

DackSter94 Posted December 19, 2019 Share Posted December 19, 2019 Helicopters can't be in the notch because of their rotor Oh they sure can be for many other dcs modules(if not all (don't have f-16/18, so can't speak for those)) LOOK MA, NO HOOK Link to comment Share on other sites More sharing options...
GIGA_HORSE Posted December 19, 2019 Author Share Posted December 19, 2019 Try set your radar to medium PRF. Its working now. it doesn't work, i've tried. If you can, please upload a video demonstrating how to do it. The only way I've managed to have a helicopter show up on my radar or lock it up is after I fired an SD-10 at it Mad dog style, so idk if SD-10 is broadcasting to mothership or what, but unless I fire an SD-10 first within a visual range there is no way I can have it show up on the radar Link to comment Share on other sites More sharing options...

Not sure what I did but pretty sure it was on medium PRF in TWS mode. I'll try again when i have time. Mastering others is strength.

dorianR666 Posted December 19, 2019 Share Posted December 19, 2019 this is a long living painful issue in DCS. radars in other modules also cant see slow flying helis, even though a heli with running rotors should be visible from 100 miles away even if sitting on the ground, as its doppler shift is massive in all directions. perhaps not jf-17 issue. hornet does the same.

DackSter94 Posted December 19, 2019 Share Posted December 19, 2019 just make helicopter steam at 130 knots ,you should be able to pick it up :) LOOK MA, NO HOOK Link to comment Share on other sites More sharing options...
foxwxl Posted December 20, 2019 Share Posted December 20, 2019 For some balance reason, Helos in dcs is hard to pick up by radar if they're not moving too fast. The doppler shift of the rotor may not currently considered in DCS, the HELOs DO notch the radar. So it's not the JF17's radar problem, U can encounter the same problem with APG-73 and APG-68.

Oceandar Posted December 20, 2019 Share Posted December 20, 2019 Actually the Hornet has no problem like the Jeff has. I made simple mission with helo speed with 86 knots and the Hornet could track it but Jeff did not. I'm aware of radar cant track helo below 70 knots but this helo was on 86 knots. And what balance you're talking about ? Mastering others is strength. Mastering yourself is true power. - Lao Tze Link to comment Share on other sites More sharing options...
AeriaGloria Posted December 20, 2019 Share Posted December 20, 2019 (edited) Well do we know the exact speed of the notch filter on JF-17?

And what balance you're talking about ? So why is the helo invisible below 70 kts on APG73? Because they entered the notch filter which they shouldn't. Even the helo is hoving, the fast rotating blades on their head are still creating obvious doppler shifting with patterns. This doppler shift should be detected / tracked by morden A2A radar. Can U do this now in DCS ? No, U couldn't. That's the balance to give the helo players some cover. Deka Ironwork Tester Team Link to comment Share on other sites More sharing options...
AeriaGloria Posted December 20, 2019 Share Posted December 20, 2019 It would be balance if it was intentional. I think it’s just simplistic RCS modeling going back to LOMAC days Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com Link to comment Share on other sites More sharing options...
Ranma13 Posted December 20, 2019 Share Posted December 20, 2019 AeriaGloria is right, it's not about balance, it's about DCS not modeling rotor blade doppler reflections. The unintentional side effect is that a helicopter flying slow and low is almost invisible to radar because only the body of the aircraft is taken into account.

Pikey Posted March 6, 2020 Share Posted March 6, 2020 There are clear accounts of rotor blades shining bright on doppler returns, they are literally huge bats whacking energy in all directions. Unfortunatley, the DCS filter looks at the aircraft speed and disregards the rotor effect.This should be fixed across the board in DCS. ___________________________________________________________________________ SIMPLE SCENERY SAVING * SIMPLE GROUP SAVING * SIMPLE STATIC SAVING * Link to comment Share on other sites More sharing options...
dorianR666 Posted March 6, 2020 Share Posted March 6, 2020 from what i could find, this was reported multiple times over the last 4 years at least. minimal chance of ED fixing this. CPU: AMD Ryzen 5 1600X GPU: AMD RX 580 Link to comment Share on other sites More sharing options...
