Abstract :
This paper describes the capabilities of the Quiet Interlude Processing System (QuIPS) in very shallow water (0 to 100 m) against undersea (mini subs, Autonomous Underwater Vehicles (AUVs), swimmer delivery vehicles (SDVs), etc.) and surface threats. QuIPS performs Matched Phase Matched Field Processing (MPMFP) in real time and data fuses contacts with nonacoustic, remotely sensed data and traditional plane wave acoustic data. No existing system has the capability to detect, classify, and track such threats in very shallow, noisy near shore and harbor environments where the acoustic arrivals at low frequencies are not plane wave.
