Radar losing contact after 15"

[Redglyph]

Hello,

 

DCS version 1.5.5.59744.197

 

I'm following two aircraft, same level, I'm about 3-4 nm and they're at my 12.

 

If my radar was already switched on (EM), nothing appears on it. If I switch it off, then on PCH for 1-2 seconds, then on EM, I see the contacts for 15", after which they disappear again. I can repeat that as many times as I wish, it's pretty consistent.

 

Is that normal behaviour? Perhaps I missed something, but I'm pretty sure it wasn't behaving like that earlier. How can I keep those contacts permanently?

 

The radar is set as follows, though I've tried different settings:

- med PRF

- 4 bars

- 60° sweep

- 5 nm range

You'd tried it first on HIGH PRF, doesn't you?

[Redglyph]

I did, and since the targets are visible after cycling PCH/EM I don't think it's a matter of not getting the echo. They just disappear after 15".

 

It's apparently the same in DCS 2, perhaps it's on purpose, I have no idea.

 

Another annoying thing is the TDC cursor, it doesn't seem possible to limit its speed, and it's frankly too fast to use for me. It seems all-or-nothing despite being mapped on an analogue device.

Are you at low altitude and same speed as the targets you're following? If so then this is a somewhat accurate representation of side-lobe clutter that can appear in this situation. Somewhat because I don't know how the RDI filters side-lobe clutter, but it is a problem in the N019/N001.

[Redglyph]

It's not at low altitude, the same is happening at 20k or 5k.

Try the different radar settings aka ENT or whatever the bottom switch is on that button.

:huh:

 

It seems that since I've mapped the slew TDC controls, this problem disappeared. Ah well.
