本文在文献[1] 所建杂波模型的基础上,进一步研究空时自适应处理对双基地机载预警雷达杂波的抑制问题.深入分析了双基地机载预警雷达杂波距离多普勒特性,进而提出了一种基于距离多普勒补偿的空时二维自适应处理方法.理论分析与计算机仿真表明,该算法能有效实现工作于低重频时双基地机载预警雷达杂波抑制.
Abstract
In this paper,clutter suppression for bistatic airborne early warning(AEW) radar is studied farther by space-time adaptive processing(STAP) based on the clutter model presented in[1].The range-Doppler clutter characteristics are analyzed in detail in this paper.In the case of LPRF,a novel space-time adaptive processing approach based on range-Doppler compensation is proposed to suppress the clutter for bistatic AEW radar.The validity of the approach is illustrated by theoretical analysis and computer simulation.
