Radar signal processing using forward-backward matrix

Aspects of the present disclosure relate to a radar signal processing apparatus and method. As may be implemented in accordance with one or more embodiments, a digital signal representing a received reflection of a radar signal transmitted toward a target is mathematically processed to provide or construct a matrix bundle based on or as a function of a forward-backward matrix. An eigenvalue of the matrix bundle is calculated, and an estimate of a direction of arrival (DoA) of the target is output based on the calculated eigenvalue. 本公开的方面涉及雷达信号处理设备和方法。如可根据一个或多个实施例实施的，数学处理表示朝向目标发射的雷达信号的接收反射的数字信号，以提供或构建基于前向-后向矩阵或作为前向-后向矩阵的函数的矩阵束。计算所述矩阵束的本征值，并且基于计算所得本征值输出对所述目标的到达方向(DoA)的估计。
