[REQ] US APR Radar/Signal Detection Ability

There is no bearing information given when a radar detector picks up a contact, only a message along the lines of "radar signals detected."

Agreed and the SD radar A-Scopes didn't give bearing, but they did give range. It's not about easy. It's about realism. With an A-Scope I know how many air contacts there are, how far out they are, and how fast they're approaching my position. SHCE had this and I miss it sorely.

The game should give a bearing for the detected emissions, too. That's the beauty of DF.

Discovered some U.S. Submarines were being upgraded with AN/APR-1

Info listed about it at this site: http://hereford.ampr.org/millist/m3.html

AN/APR-1

Radio receiving set, Countermeasures, 40-1000 MHz (harmonics to 2850 MHz), 12 VDC @ 6.25 A. Major component CPR-46ABC or AM-12/APR-1 and TN-1B, TN-2B and TN-3B tuning units, Replaced by AN/APR-4 and AN/APR-14.

AN/APR-4 is dated 1943 info listed here: http://www.radiomilitari.com/apr4.html

[quote]By late 1944, many submarines had limited radar detection installations called radar countermeasures (RCM), although they never included jammers. Plaice's (SS-390) antenna blocked out here appears to be an AS-44, which detected microwave (S-band) signals at 1000-3500 MHz seerving an APR-5AX or SPR-2. Both antennas were omnidirectional, and both could be connected to a pulse analyzer (SPA-1), from which the signal's pulse repetition rate and pulse width could be read. If the radar was a known type, this figure could identify it.

I think Batfish has 4 or 5 APR / TN sets in the con and another bigger set in the radio room. The bigger set probably analyzed what the smaller receivers detected. Each APR box has a limited frequency range and probably a modulation type, as well (AM, FM, side-band, etc.).

Batfish also has a Friend or Foe Indentification system in the con. There's a black contactor switch which used to be hooked up to explosive charges inside the FFI unit, in case of the chance of being boarded/captured.

I'll have to post some pictures of all of this stuff. Then, you'll really appreciate how much stuff they crammed into the con. The cons portrayed in the game are way too open.

Man that sounds neat! Please post some of the pictures when you find the time to do so Sarsfield, I know I'd enjoy seeing the sets.
