We address the design of GLRT-based, space-time radar detectors in presence of a communication signal. We consider a disturbance that is either spatially correlated and temporally white or spatially and temporally correlated. The former case assumes that the disturbance is modeled in terms of a scalar autoregressive filter while the latter case exploits a vector autoregressive filter. The filter parameters are unknown while the order is a design parameter. Finally, the direction of arrival of the communication signal is known. The analysis, conducted in comparison to natural competitors, also under mismatched conditions, shows the potential of the proposed approach.

针对不合作频谱共享场景的无需辅助数据的自适应雷达检测


我们致力于在存在通信信号的情况下设计基于 GLRT 的时空雷达探测器。我们考虑空间相关且时间白色或空间和时间相关的干扰。前一种情况假设扰动是根据标量自回归滤波器建模的，而后一种情况则利用矢量自回归滤波器。滤波器参数未知，而阶数是设计参数。最后，通信信号的到达方向是已知的。该分析是在不匹配的条件下与自然竞争对手进行比较，显示了所提出的方法的潜力。
