Improved Detection Performance of a Transmitted-Reference UWB Radar System with Unequaled Amplitude Pulse for Vehicles

This paper analyzes the performance of a proposed transmitted-reference (TR) UWB radar system for vehicles. To improve the detection performance of the previous TR-UWB system, the amplitude of a reference pulse can be changed to order to increase the energy-to-noise ratio. Finally, the characteristics of the proposed TR-UWB system are evaluated by simulation. In the AWGN channel, simulation results show that the detection probability of the proposed TR-UWB system with a scaling factor of 2, 10 is an improvement of approximately 3, 6dB, respectively, over the previous TR-UWB system . In the IEEE 802.15.4a Outdoor LOS channel, the detection probability of the proposed TR-UWB system, with a scaling factor of 10, is an improvement over the previous one by approximately 10dB.
