A New Algorithm for Sparse Frequency Waveform Design with Range Sidelobes Constraint

To suppress narrowband interferences, sparse frequency waveform can be transmitted by wideband radar systems. It suffers the high range sidelobes. A new algorithm for sparse frequency waveform design with range sidelobes constraint is proposed. The approach affords much better frequency stopband suppression by flexibly controlling sidelobes constraint using Weighted integrated sidelobe level (WISL) metric. The approach is computationally efficient and can suit the more general Peakto- average power ratio (PAR) constraint. An extension to Multiple-input multiple-output (MIMO) radar case is also presented.
