Waveform synthesis via alternating projections with ambiguity function, peak-to-average power ratio, and spectrum requirements

A method is presented which synthesizes a radar waveform with desirable ambiguity function properties, while simultaneously meeting user-specified requirements on the waveform's peak-to-average power ratio (PAPR) and spectrum. The result is a radar waveform optimization providing desired range-Doppler resolution, spectral compliance, and power efficiency capability. The waveforms are generated via projection and are not constrained to any set of basis functions. A brief overview of the projection process is given, as well as the outline for the methodology to ensuring PAPR and spectral compliance. Simulation and measurement results show successful operation of the approach.
