In this paper, the construction of a baseband signal processing algorithm for unmanned aerial vehicle (UAV) detection radar by using continuous linear frequency modulation (FMCW) signal is presented. On the basis of the built algorithm, the article presents the contents of simulation research in Matlab environment, and conducts experimental research by designing and deploying signal processors on the technology platform FPGA. The results of the study show that FMCW radar can be used to distinguish UAV targets from normal targets by the micro Dopple signature. The signal processor is the basis for building a complete UAV detection radar in the future.
