Performance analysis of UWB radar for vehicle in multi-user environments

This paper analyzes the performance of UWB radar for vehicle in multi-user environments. To evaluate the probability of detection in UWB vehicular radar under a multi-user environment, we use the transmitter and receiver architecture of UWB radar system model. The system model consists of three major parts: a transmitter, multi-path channel and a receiver. Finally, the characteristics of vehicle-mounted UWB radar are evaluated by simulation. Simulation results show that the detection probability is reached with 1 in AWGN channel when relative distance is 120 m and the probability of detection becomes 0.55 when relative distance is 47 m in the IEEE 802.15.4a CM1.
