Radar Mode benefits/drawbacks

[ouseler]

Is there any benefit to being in a radar mode other than HFR?  From the manual, the ENT (interleaved) mode combines the HFR and BFR modes.  However, the manual also says that BFR is just the Raw Radar returns with no filtering and that no lock can be attained in BFR mode.  So what is the benefit of ENT or BFR over HFR?

I think and have understood it in such a way that several factors come into play here and it also depends on the respective situation. You have to 'play' with the pulse repetition frequency a bit to get the best result. To say I only use HFR or only ENT... would be wrong. Like I said, that's my understanding so far.

There isn't much use of BFR for A/A. You can see notching aircraft in look-up, but yes, it's a raw return and you can only initiate a lock on the BFR sweep below 10NM.

BFR might be useful for navigation (ground mapping), locating ships, and weather (not applicable as no local rainfall yet in DCS). Large group of ground units in a very clear terrain (desert) might be spotted, too.

ENT alternated between BFR and HFR if you want to combine one of those uses while watching A/A traffic.
