I've discovered that I am unable to pick up F-5Es on radar in the Hornet despite being at comparable altitudes. I was able to lock up TGT 1 and 2 with Boresight, TGT 3 using Vertical Scan as I overshot while testing a different radar setting as discussed on the DCS Discord.

 

This mission was originally against MiG-15s and, without doing anything special, I was able to detect the MiGs out to 70nm+, yet when I change them to F-5Es I am unable to detect them on radar at any range.

 

Track attached.

Hi cailean_556

 

No issues here, I can detect and lock with no issues.

 

In this example I just changed to a 40 degree scan and when it came into the 40nm range it was on the radar.

Set a F-5 in a racetrack, and you will see that the radar can sometimes detect it, and sometimes not, depending of the angle.

 

I am not a specialist of military radar, only the weather radar on my 737, but it seems to be a correct behaviour.

 

But maybe it is still a bug in the radar, not sure.

While on a racetrack, it will sometimes fly either at zero closure speed with respect to you or fly perpendicular to your heading (will be notching you). In both cases, the Pulse Doppler radar of the F-18 will have a hard time detecting it, that's a limitation of PD radars, since they rely on Doppler shifts and speed filters.

For reference, in DCS F-18, the detection range for a beaming target is about 2/3 the detection range if that same target were flying toward you. Eg. a Mirage 2000 detects at 50ish miles (moving 400kts) head-on and 35ish miles beaming. This might be different for different planes because of their shape, but they will all be in that ballpark.
