Motion Energy Sensor Fusion with Guidance Laws for Seeker Discrimination

"Computational Sensors Corp. (CSC) will examine mid-course interceptor data fusion approaches for guidance divert direction with spatio-temporal motion energy filtering. The domain of validity of a motion energy approach must be determined through thesensor suite target state estimation accuracies required by the guidance laws. CSC proposes to accomplish this through the implementation of a Fisher Information Matrix (FIM) analysis of realistic simulated engagement scenarios in order to determinetarget state observability from the sensor data. In previous work, CSC developed a massively parallel, real-time video processing system capable of agile, wavelet-like spatial frequency filtering using low power analog silicon retinas in a programmablemulti-chip architecture. Subsequent work has demonstrated the utility of spatio-temporal filtering in mid-course threat cloud RV/decoy and RV/clutter discrimination. In Phase II, a more thorough application of the FIM analysis developed in theproof-of-concept Phase I work will be performed in addition to applying S-T filtering to hardware-in-the-loop (HWIL) scene simulator application of the interceptor guidance laws. Analog VLSI spatio-temporal filtering and motion energy analysis hardware hasthe potential to provide NMD interceptor sensing platforms with additional onboard sensor processing capability for improved RV/decoy discrimination, closely spaced object (CSO) resolution and threat cl
