PRG Gunfire Rockets IR is Detected by which system?

• A. AN/AAR-57 CMWS
• B. CW radar
• C. HFI-enabled CMWS
• D. Pulsed radar

Answer: (C)

Detecting infrared threats requires sensors that directly monitor IR signatures, especially when the target is a short, fast-emitting source like a gunfire rocket plume. The best choice here is an infrared missile-warning system that is enhanced with high-frequency imaging, because that capability increases temporal resolution and sensitivity to quick, transient IR events. The HFI-enabled CMWS can pick up those brief IR cues and warn the aircraft so countermeasures can be deployed in time. Other options rely on radar signals or general CMWS hardware without the high-speed IR imaging improvement, so they wouldn’t be as effective at detecting the rapid IR emission from PRG gunfire rockets. In short, the IR threat is best detected by an HFI-enabled CMWS due to its ability to resolve fast, infrared signatures.
