To suppress narrow band interferences, sparse frequency wave form can be transmitted by wide band radar systems. It suffers the high range side lobes. Anew algorithm for sparse frequency waveform design with range side lobes constraint is proposed. The approach affords much better frequency stop band suppression by flexibly controlling sidelobes constraint using Weighted integrated sidelobe level (WISL) metric. The approach is computationally efficient and can suit the more general Peak to‐average power ratio (PAR) constraint. An extension to Multiple‐input multiple‐output (MIMO) radar case is also presented.
