Robust Multistatic Sea-based Radar

Physical Sciences Inc. (PSI) proposes to develop, evaluate, and test its candidate architecture for multistatic radar for Ballistic Missile Defense (BMD). The innovative architecture is based on nonlinear Kalman Filter data fusion with multiple dynamical models with compensation for ship platform errors, and a parallelized multiple hypothesis tracking/association methodology (MHT). The key result of the effort will be demonstration of the improved track quality (including probability of establishing track following cue, time to firm track, track error, and track purity in a cluttered/multitarget situation) for a BMD engagement in the ascent or midcourse of flight, including a raid scenario, using realistic models for ship motion and clock errors and in-service radar waveforms and signal processing tools. The effects of system constraints (finite communication bandwidth for resource management and co-registration of radar platforms) will be tested and compared using a software simulator of the multistatic architecture. The planned effort will integrate the algorithms and software developed during the Phase I with new developments (error compensation and MHT), and enable detailed (I/Q level) simulation of multistatic radar returns. To enable and implement the intensive processing needed for key functions and algorithms, a high performance computing solution using COTS equipment will be implemented.
