Radar Waveform Optimization For Ambiguity Function Properties And Dynamic Spectral Mask Requirements Based On Communication Receiver Locations

A dynamically determined spectral mask for radar transmission, based on changing wireless communication handset locations and maximum acceptable handset interference power levels, is used to optimize the radar waveform. The alternating projections optimization is based on the spectral mask and a minimization template for the ambiguity function, which provides range/Doppler combinations for which the ambiguity should be minimized. This optimization is continually re-performed as the spectral mask is adjusted based on handset location changes. Several different scenarios are demonstrated in which this optimization is shown to be successful. This algorithm will use information about communication handsets provided through an ad-hoc network to tune the radar waveform.
