Multi-sensor placement to exploit complementary properties of diverse sonar waveforms

Distributed multistatic active sonar systems have the potential to greatly improve surveillance capability against threat submarines. The geometric diversity of such systems provides an increased number of complementary detection opportunities to counter the underwater threat. The utilization of both Doppler sensitive and insensitive waveforms within such a multistatic network further improves the detection diversity and provides a more robust surveillance capability. This paper describes the issues relevant to achieve this detection diversity, and shows the potential improvements of this approach. A simplified sonar signal excess model is described, which provides a capability to evaluate distributed sensor placements using both waveform types
