Experimental Research on the Moving Target Detection with A K-Band Radar

This paper mainly introduces the moving target detection experiment using a linear frequency modulated continuous wave (LFMCW) radar. First, the target detection theory is presented. Then, the designed system including radar, VCO generation circuit and DSP implement are introduced. Finally, the system is used to detect the corner reflectors, vehicles and pedestrian targets to verify the effectiveness of the algorithm. The test results show that the speed measurement accuracy is less than 2km/h, the angle measurement accuracy is less than 1 degree, and the distance measurement accuracy is less than 1 meter.
