This paper examines the problem of cancellation of cochannel interference (CCI) present in the same frequency channel as the signal of interest, which may bring a reduction in the performance of target detection, in passive bistatic radar. We propose a novel approach based on probabilistic latent component analysis for CCI removal. The highlight is that removing CCI is considered as reconstruction, and extraction of Doppler-shifted and time-delayed replicas of the reference signal exploited fully as training data. The results of the simulation show that the developed method is effective.

被动双基地雷达中使用概率潜在成分分析消除同频干扰

本文研究了在无源双基地雷达中消除与目标信号相同的频道中存在的同频道干扰（CCI）的问题，该问题可能会导致目标检测性能下降。我们提出了一种基于概率潜在成分分析的CCI去除新方法。突出的一点是，删除CCI被视为重建，提取参考信号的多普勒频移和时间延迟的副本被完全用作训练数据。仿真结果表明，该方法是有效的。
