ECM - Sensors

Featured Replies

 

What is exactly "area" ECM? because, AFAIK, Type-D, FLIR and Laser (Sub-Type) pods aren't functionnal at all.

 

In fact, what is a "Type-D" pod?

 

About "sensor flags" in the aircraft annex, FLIR allow to detect ships but not planes and IRST detect aircrafts not ships, isn't the opposed IRL?

Thx,

Jan

Ok, done some tests about Radar's PD.

Tested ECR-90 (SS (airborne), LD-SD) at about 15 different PD values.

It seems that from 9 up to 200, detection range is the same, below 9, detection range drop to less than 50%, at PD 0, it seems that there is no radar detection or at lowest range than viual detection (was 3nm).

 

Will test airborne(360) tomorow. ("tomorow" is relative, since, technically, we are already "tomorow" <_< )

 

Maybe Tony can confirm/ infirm these results?

 

I'm heading to my bed with a PD of about 50% because my eyes are closing themselves :blink:

Cheers,

Radar PD is used with the die roll (random number 1 to 100) to determine if a detection is made assuming all other prerequisites are met (i.e. radar model says a detection is possible)

 

So you should see general patterns but different results on each test with a given PD (PD should be between 1 and 100 of course, a PD > 100 doesn't make sense, nor does 0 for that matter)

Hm, ur explanation sounds very good but how can the detection range variations been so low with so differents PD values?

(no more than 7nm with PD 90 and 9).
