Does Falcon BMS implement infrared counter counter measures for infrared missiles?

Detection methods -

Rise Time: Measures the target’s energy level. A sudden increase within a fixed time window triggers the IRCCM.

Spectral: Uses a two-color switch to compare energy levels in different bands. A large jump in one band compared to the other indicates a flare

Kinematic: Detects the rapid change in line of sight due to a flare’s quick deceleration. Works best from the side.

Spatial: Uses the physical separation of the flare and target to discriminate. Two hot objects on opposite sides of the field of view activate the IRCCM.

once detected it can take multiple different responses -

Memory: Maintains the missile’s original trajectory while rejecting flare data until the flare leaves the field of view or the switch times out

Push Ahead: Propels the seeker forward, causing the flare to leave the field of view faster.

Push-Pull: Moves the seeker back and forth to align with the coolest part of the infrared spectrum, avoiding the flare.

Sector Attenuation: Uses an attenuation filter to reduce sensitivity in a portion of the field of view, specifically below the target.

FOV Gating: Limits the seeks FOV to filter out the flare’s effects

Electronic Fuel Division Gating:
Time Phase Blinking:

the aim-9m uses rise-time to detect flares, and the memory method to mitigate the flare effects until the target can be reacquired

r-73 uses the spatial method to detect, and FOV gating to mitigate

@JollyFE

radar being active sensor is different than passive sensors,

also war thunder has an army of info gatherers lol

excerpt -

Conclusion and Proposed Fix
The PL-8B's IRCCM system relies on two mechanisms: 
1. Signal memory-based flare discrimination (functionally analogous to the in-game "seeker shutoff" mechanic). 
2. Reduced tracking FOV (≈1°) to limit flare re-entry post-separation.

@JollyFE

everything in a game i a simplification on what happens physically, the bms (nor any “games”) radars aren’t using FFTs to process the pulses of each scheduled beam in their radar model. what i am saying is that flare chance is … silly, and even war thunder’s fidelity ( an arcade game through and through ) in this regard is better. so it is possible, and as a software engineer, if you have an accurate amraam with its nuance, the implementation of FOV gating and sensor shutoff is trivial.

@molnibalage

War thunder has done a pretty good job, they’ve implemented the Rise Time, and Spatial detection methods, and the FOV gating and Seeker shutoff as mitigation methods.

I wouldn’t imagine BMS could implement everything in one go, but it wouldn’t be that hard to do it in small bite size steps, and anything is better than some “flare chance”, or chance based logic

i haven’t ready anything by hpasp, i play warthunder from time to time, and noticed that the irccm was actually real when looking at replays and wondered if bms had the same but i’ll look for his doc.
