描述了一种空时自适应处理（STAP）方法，该方法仅使用机载雷达的主波束或和（/spl Sigma/）和差（/spl Delta/）通道来自适应抑制联合角度多普勒域中的杂波。这种方法称为 /spl Sigma//spl Delta/-STAP，可显着降低系统实施成本，因为它只需要两个数字化通道，并且适用于相控阵和连续孔径机载雷达系统的升级。结果表明，/spl Sigma//spl Delta/-STAP 提供了接近最佳的性能，并且比其他方法需要更少的样本支持，这对于在严重非均匀杂波中成功运行至关重要。
A space-time adaptive processing (STAP) method is described which uses only the mainbeam or sum (/spl Sigma/) and difference (/spl Delta/) channels of a airborne radar for adaptive suppression of clutter in the joint angle-Doppler domain. This method, called /spl Sigma//spl Delta/-STAP, dramatically reduces system implementation cost, as it requires only two digitized channels, and is applicable as an upgrade to both phased array and continuous aperture airborne radar systems. It is shown that /spl Sigma//spl Delta/-STAP offers near optimal performance and requires much smaller sample support than other approaches, which is critical for successful operation in severely nonhomogeneous clutter.
