机载非侧视雷达的杂波抑制是一个具有挑战性的问题。提出了一种结合高程鲁棒Capon波束形成（ERCB）和二维方位-多普勒空时自适应处理（STAP）的算法，实现机载非侧视雷达的杂波抑制。该算法通过放置距离相关的空点来消除距离相关的杂波，并通过二维方位多普勒STAP方法抑制剩余的距离无关杂波。数值算例验证了该算法的有效性。
Clutter suppression for airborne non-sidelooking radar is a challenging problem due to the range-dependent clutter. In this study, an algorithm combining elevation robust Capon beamforming (ERCB) and two-dimensional azimuth-Doppler space-time adaptive processing (STAP) is presented to realise clutter suppression for airborne non-sidelooking radar. The presented algorithm can place range-dependent nulls to eliminate the range-dependent clutter and the residual range-independent clutter can be suppressed by two-dimensional azimuth-Doppler STAP methods. Numerical examples are given to demonstrate the effectiveness of the presented algorithm.
