Design and Performance Analysis of Triangle Wave Radar based on SDR platform

This paper first introduces the principle of ranging and velocity measurement of the triangular linear frequency modulation continuous wave radar and the basic structure of the SDR platform briefly. Based on this, it elaborates on the triangular wave radar signal processing algorithm based on the SDR platform. Based on given emissive signal and echo signal, the frequency spectrum of the difference frequency signal is calculated according to the simulation target. Then, according to the processing steps of the algorithm, including mixing, FFT, CFAR, spectrum matching, etc. The algorithm is simulated by MATLAB. The radar signal processing algorithm is verified and tested by the method of baseband echo signal testing.
