Multi-static Processing

The Ultra Multi-Static Active System (MSA) comprises a field of transmit and receive sonobuoys and the necessary processing to detect and track targets without overloading the operator. It uses multiple sources and receivers, positioned in different locations, so that echoes from active sources are picked up by a pattern of receivers, which take advantage of multiple returns from the submarine at multiple aspects. These multi-static combinations of sonobuoys are collectively exploited to produce an accurate target track.
