A Quai-CW Radar Waveform Design Based on Multimode Arbitrary Code Sequence to Avoid Echo Eclipse

In order to solve the echo eclipse problem in phase-coded quasi-continuous wave(quasi-CW) radar,the echo eclipse is quantitatively analyzed by using echo eclipse ratio function and main lobe to side lobe ratio.On this base,a phase-coded waveform design method based on multimode arbitrary code(MAC) sequence and long-short pulse width is proposed,and an example of quasi-CW radar signal design based on this method is presented and simulated.Simulation results show that the echo eclipse problem is effectively solved as well as the whole range target can be detected simultaneously.
