摘要：This paper analyzes the detection performance of new Transmitted-Reference (TR) automotive UWB radar using unequaled amplitude for vehicles. To improve the detection performance of a traditional TR-UWB system, the amplitude of a reference pulse can be changed to increase the energy-to-noise ratio. Finally, the characteristics of the proposed TR-UWB radar are evaluated by simulation. And the performances of the proposed radar are compared with a coherent matched filter and a traditional TR-UWB system. For special case when SNR=3dB and =6, we can assert that the detection probability of the proposed TR receiver is approximately a 19% increase compared with that of the conventional TR receiver when the probability of false alarm is 0.5.
