Multi-Mission Waveform Design

"This project is aimed at improving the detection of slow-moving ground targets by use of waveform agility controlled by a process that optimizes the waveform ambiguity function. Optimization is derived from the "scene" - the clutter and target environmentin which the radar is operating - using the instantaneous data from the radar to construct clutter maps and signal tracks that drive the optimization process. Waveforms are selected via a multi-step scheduler from a library that includes conventional andnovel (multiwaveform) types sufficient to provide the required wide variety of ambiguity functions. The main thrust of the project is to develop a prototyping simulator that will permit estimation of the performance of the system in a variety of clutterand target scenarios. The resultant techniques are expected to have a wide range of applications, for example in airborne ground surveillance radars, in maritime surveillance, and in space-based radars. A commercialization plan is proposed that willassess the relevance of the system to existing and emerging radar systems in consultation with the potential customer base and with radar system suppliers. To support the commercialization activity, the studies will include investigation of performance ofthe waveform selection scheme in clutter and target environments representative of all three major fields, and will address implementability issues to minimize identifiable risks in any
