N2 - With the widespread application of unmanned aerial vehicles, higher requirements have been put forward for the detection of small targets moving at high speed. In this paper, we implement a millimeter wave Frequency Modulated Continuous Wave (FMCW) radar system with dual-receive channels to detect target motion parameters. In the radar system, a novel signal is designed to be composed of two FMCW signals whose instantaneous frequencies are symmetrical about carrier frequency, so as to get the estimation value of the targets' distance and radial velocity using doppler shift. Besides, signals of different periods are transmitted alternately to facilitate the removal of virtual targets. Furthermore, the height information of the target can be obtained through the interference of the signals received by the two channels. Based on the theory above, simulation results are provided to validate the effectiveness of the proposed approach and evaluate the performance of the radar system.
