The AC-130 Gunship is extremely vulnerable to MANPAD attacks/other enemy ground fire when operationally employed. A solution is needed to reduce aircraft/aircrew risk while maintaining operational effectiveness. Through AFRL/SN initiatives, DRA has developed/demonstrated a Passive Ground Moving Target Indication (PGMTI) concept that detects/tracks ground moving targets with low false declaration rates. Phase II PGMTI will extend the Phase I effort by incorporating a video data remote processing capability onboard a surrogate UAV. Utilizing existing sensors onboard UAVs (like Predator), Phase II will add processors which detect/track/display ground moving targets to an appropriate operator. Technical advantages are: Real-time Information, not raw data, is forwarded for human interpretation Every pixel of data in view of the sensor is scrutinized by the PGMTI system, not just what an observer could see on a monitor Minimal transmission bandwidth is required for PGMTI as raw data is processed onboard the UAV. Only moving targets are down-linked to an operator Operational advantages are: Shorter engagement times/reduced exposure to hostile fire for AC-130 Gunships as the UAV detects/tracks moving targets/enemy fire, then passes this data to the Gunship for immediate targeting PGMTI capabilities on UAVs can greatly assist with all operational missions
