Abstract：In this paper the characteristic of several typical HF radar waveforms are synthetically analyzed and compared.A new waveform with interrupted spectra is presented to improve the narrow continuous bandwidth usable in heavily congested electromagnetic environments.By cutting off the interference spectrum based on the result of the electromagnetic environment surveying system,HF radar could make use of the fractional silent spectra.This would greatly improve the radar's anti-jamming ability and effective bandwidth.Moreover,an improved adaptive targets echo reconstruction algorithm is used.Simulation results show that it could successively suppress the high sidelobe with this waveform.
