Passive IR sensors. That's right you bitches. Iran's got 'em turned upsidedown

I politely tell the officers that I'm an operator for the law now. (http://www.autoadmit.com/thread.php?thread_id=5853172&forum_id=2most#49792008) |

| Technique | How it helps | |-----------|--------------| | Dual‑band operation (MWIR + LWIR) | MWIR captures hot exhaust (high ΔT) while LWIR captures skin contrast; the system can switch to the band with the best SNR for the current range/conditions. | | Cryogenic optics & detectors | Cooling the detector to 77 K (or lower) reduces dark current and NEP by 2‑3 orders of magnitude, pushing the detection limit farther out. | | Large‑aperture, low‑f‑number telescopes | A small f‑number (e.g., f/1.2) increases the solid angle Ω captured, boosting photon flux. | | Image‑fusion with radar | Radar provides coarse range/velocity; IR‑ST supplies high‑resolution bearing and classification. Fusion allows the IR sensor to operate at lower SNR because the track is already known. | | Adaptive background subtraction | Real‑time modeling of sky temperature and cloud cover reduces false alarms and lets weaker targets emerge. | | Staring‑mode with temporal averaging | For slowly moving aircraft (e.g., high‑altitude UAVs), a few seconds of frame averaging can raise SNR without excessive motion blur. | | High‑gain pre‑amplifiers & low‑noise read‑out ASICs | Modern FPAs integrate on‑chip amplification that preserves photon‑count statistics. | | Deployable optics (e.g., telescopic booms on UAVs) | Extends aperture size without increasing platform drag, allowing longer‑range detection from airborne platforms. | |
