摘要：

In this paper, a linear frequency modulated continuous wave (LFMCW) radar system was designed and established for detecting the distance and velocity of people and vehicles. The radar operates at 35 GHz with the maximum sweep frequency band of 2 GHz and uses triangular wave modulation. Background learning method is introduced to improve the system performance. Learning and recording the stationary background results after Moving Target Indication (MTI) filter is used as the threshold value for detecting moving targets. The designed radar system measured the distance and velocity of walking people and the speed error is less than 0.5 m/s.
