摘要

针对共形阵机载雷达的杂波抑制问题

提出了一种稳健的空时自适应处理(STAP)方法.该方法首先将待检测距离单元中所含的目标信息剔除

然后利用自回归(AR)模型来描述该单元杂波特性

最后通过求取AR模型系数得到待检测距离单元中杂波正交子空间来对消杂波.该方法不受雷达工作模式影响

适用于任意形状的阵列天线

且不存在干扰目标问题

因此较已有的多普勒补偿类、直接数据域和参数化等STAP方法更为稳健.仿真结果验证了该方法的有效性.

Abstract

A novel robust space-time adaptive processing (STAP) method is proposed to eliminate clutter in airborne radar with conformal antennas array.This method filters the target information of range cell under test based on the phase characteristic of target.Then the clutter characteristic are described by constructing AR model and the subspace

which is orthogonal to the clutter and jamming space

is obtained to eliminate clutter.Compared with conventional Doppler compensation methods

direct data domain methods and parametric methods

the proposed method is more robust because its performance can’t be influenced by radar working mode and outliers

and it can be applied for arbitrary array.The simulation results demonstrate its effectiveness.
