非正侧面阵的近程STAP

空时自适应处理(STAP)作为一种地杂波环境下机载雷达自适应检测小目标的方法已得到广泛研究，非正侧面阵也是其中的一个重要方面。由距离变化引起的地杂波脊的非平稳性是非正侧面阵STAP在近距性能下降的主要原因。利用扩展样本矩阵求逆(ESMI)

Close Range STAP for Non-Broadside Array

STAP has been widely studied for airborne radar as an approach to adaptively detect small target competing with ground clutter. Non-broadside array is also an important aspect of STAP. The non-stationary clutter ridge as a function of range accounts for much of the degradation at close range. The use of range varying adaptive weights with the extended sample matrix inversion(ESMI)technique 1] is widely applicable to a number of non-stationary problems including the case of the clutter ridge encountered in non-broadside array STAP. This paper further considers a new close range processor for non-broadside array, the so-called exponent extended sample matrix inversion(EESMI), which describes the change of weight as a exponential function. By that, the desirable performance of the close range processor is observed.
