A low side-lobe waveform design method for random hopping frequency signal

In this paper, a waveform design method utilizing the low maximum side-lobe in the synthetic range profile as the criterion for the random hopping frequency radar is proposed. Firstly, the center range ambiguity function which represents matched filtering output of transmitted signal is derived. And the output signal to noise ratios (SNR) of it and the synthetic range profile based on correlation processing are investigated. Then, the waveform design method based on uniformly splitting window function is proposed to improve the peak to side-lobe ratio of the synthetic range profile. Finally, numerous simulated experiments show that the proposed design method is effective.
