By properly transmitting pulses through the clear frequency bands, hopped-frequency (HopF) waveform can achieve a large synthetic bandwidth while avoiding complexity of wideband hardware as well mutual interference to/ from adjacent RF users.To optimally design HopF with low range sidelobes under given spectral constraints, we propose two-step-based approach in this paper.In first step, deterministic is presented to produce rough approximation optimum solution address non-convexity design.In second gradient method applied locally refine obtained step.The proposed efficient main computation step lies solving convex optimisation which be achieved polynomial time and iterative operations implemented using non-uniform fast Fourier transform.Experimental evidence suggests that near optimal remarkably little time.
