Wavelet-Based Waveform for Effective Sidelobe Suppression in Radar Signal

A new radar waveform based on wavelets is proposed. The waveform shows significant advantages over conventional linear frequency modulated (LFM) and Costas waveforms for effective sidelobe suppression. Another benefit comes from the wavelet packets, each of which occupies a subband in the frequency domain. Subband adaptation of the waveform in both magnitude and phase becomes flexible, responding to varying target and environmental conditions. The latter facilitates the development of powerful cognitive radars.
