Abstract :
This paper analyzes the detection probability of LFM-UWB radar based on Doppler frequency. The LFM-UWB radar system consists of a transmitted part and a received part and uses AWGN channel. The system model is verified through analysis and simulation. Frequency offset occurs in the received part caused by the mismatching between the received signal and the reference signal. Performance degradation of detection does not occur in LFM-UWB radar, with 30cm resolution when the margin of Doppler frequency is about 120Hz.
