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。

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.
