Slantlet Radar Waveform for Effective Side-Lobe Suppression

In this paper, a cognitive radar waveform is proposed by using Slantlet filter coefficients. The construction of slantlet waveform is introduced and compared to conventional linear frequency modulated (LFM) with the same time duration and bandwidth. The results reveal that the proposed slantlet waveform has superior side-lobe suppression than the LFM signal. As the waveform is a combination of Slantlet filter coefficients, the amplitude and phase adjustment becomes flexible in various environments. Subsequently it can be used in cognitive radar.
