摘要
针对低分辨率雷达体制下的空间目标识别问题,首先分析了空间目标的雷达特性规律,在此基础上,提出了基于高阶统计量的空间目标识别算法。计算机仿真实验表明,即使在较低的输入信噪比下,该算法依然对自旋稳定卫星、三轴稳定卫星和空间碎片等三类目标取得了比较好的识别效果。
In order to solve the problem of space target recogniton under low resolution radar system, this paper analyzes radar property of space target at first,then puts forward space target recognition algorithm based on high order statistics. Computer simulation shows：this algorithm gains good recognition effect of spin-stabilization satellite, three-axis-stabilization satellite and fragment, even though SNR is very low.
