| 摘 要： | 简要介绍了基于调频电台非合作式双基地雷达试验系统的组成,解决了两个主要直达波对消和目标检测问题。使用基于NLMS方法的非因果滤波器完成阵列多通道的时域均衡, 通过时域、空域联合处理,对消了比噪声强80 dB以上的直达波信号,对民航飞机的探测距离超过300 km。试验验证了该算法的实用性。

| Abstract: | An experimental FM radio based non cooperative bistatic radar is briefly described, and two related key techniques, i.e. line of sight (LOS) signal cancellation and targets detection, are listed in this paper. Other than algorithms appeared in most papers, NLMS based non causal filters are used to equalize the array multi channel differences. The LOS signal about 80 dB above the noise level is cancelled completely after joint time space processing. Civil airplanes are detected 300 km away. Experimental data verifies the simplicity and effectiveness of the proposed method. |
