Signal Systems Corporation proposes to use our Coherent Multi-static Acoustic Processing (CMAP) software to process the received acoustic sonobuoy data. The CMAP algorithms and software are an advanced coherent signal processing chain that is the baseline for the P-3/P-8A Multi-static Active Coherent (MAC) program and was developed under the Office of Naval Research"s (ONR) Littoral ASW Multi-static Program (LAMP). SSC will use our Multi-Static Performance Model (MSPM) simulation tool to show the improvement in detection range, time to detect, duration of track and other key metrics. Additionally, SSC has a Likelihood Ratio Tracker (LRT), which is an automated Bayesian multi-static detection and tracking fusion engine. This Bayesian processor will process the multi-static"s processors contact reports and fuse common contacts across different sonobuoys. The LRT processing is a proven method to dramatically improve the detection and false alarm characteristics of multistatic contacts and overcome the bearing ambiguity of using omnidirectional sonobuoy sensors by using the localization effect of a distributed field of omnidirectional sensors.
