Abstract

The propose of this paper is to improve the performance of Passive Bistatic Radar. The process of developed model has three steps. Firstly, the integration of the designed Passive Bistatic Radar algorithm such as coherent receiver USRP B-210, Least Mean Square (LMS) adaptive filter for noise cancellation, cross correlation for comparing similarity of two series signals and the result display on time scope for range and velocity of the targets. Secondly, the test on the overall system with the simulation targets in real time environment. Thirdly, the evaluation on the result of simulation for the range and velocity of the targets. The result of this experiment is more stable because of better synchronization receiver, noise cancellation in designed LMS which is close to the LMS simulink block, range and velocity from cross correlation for comparing similarity of the signals appear correctly. Conclusion, the simulations show that the proposed algorithms improve the performance of Passive Bistatic Radar.

被动双基地雷达探测目标距离和速度的建模与仿真在USRP B-210 SDR上的应用

本文的研究旨在提高无源双基地雷达的性能。开发模型的过程分为三个步骤。首先，将所设计的无源双基地雷达算法(相干接收机USRP B-210)、最小均方自适应滤波(LMS)降噪、两串信号相似度比较的互相关以及结果在目标距离和速度的时间范围上的显示进行集成。其次，对整个系统在仿真目标的实时环境下进行了测试。第三，对目标的距离和速度的仿真结果进行了评价。由于采用了更好的同步接收机，所设计的LMS的噪声消除与LMS simulink块接近，距离和速度从相互关系中比较信号的相似度，实验结果更加稳定。仿真结果表明，所提算法提高了被动双基地雷达的性能。
