Sensor Fuzed Weapon (SFW) within CBU-97 detects heat and scans with which sensor?

• A. Infrared (IR) sensor
• B. Radar
• C. Acoustic sensor
• D. Visible light camera

Answer: (C)

The SFW uses a two-step sensing approach to reliably identify targets. It first detects heat with an infrared sensor to locate warm engine areas. Then it scans with an acoustic (seismic) sensor to listen for target signatures and confirm the presence of a vehicle before arming. This acoustic scanning helps distinguish actual vehicles from other heat sources and clutter, making it the best fit for the sensing chain. Radar or a visible light camera wouldn’t provide the same reliable discrimination in battlefield conditions, and the system specifically relies on acoustic sensing to accompany the heat detection.
