Multi-targets pairing method of Ultra-Short-Range Radar based on motion compensation

A new method is proposed to solve the problem of multi-targets pairing of Ultra-Short-Range Radar. This method is based on motion compensation of high-speed target detection. This paper uses a hybrid signal composed of simple Continuous Waveform and Linear Frequency Modulation Continuous Waveform (CW and LFMCW) as a transmitted signal. The unambiguous velocity of a high-speed target is measured by CW beat signal, then the velocity information is utilized to compensate LFMCW beat signal to measure the target range. The method realizes motion compensation of high-speed target detection. And it can also settle the problem of multi-targets pairing. The effectiveness of the method is demonstrated by simulations.
