基于均方误差的逆合成孔径雷达干扰效果评估

为解决成像雷达的干扰效果评估问题,从均方误差的角度出发,提出一种逆合成孔径雷达干扰效果的评估方法,将干扰效果评估量化在0~1之间,能快速简洁地衡量出干扰模式的优劣。通过对射频噪声干扰模式和调相噪声干扰模式进行基于逆合成孔径雷达实测数据的干扰仿真,结果表明,该评估方法不仅大大减小了计算量,而且具有归一化、客观和定量的优点。

An Evaluation Method of Jamming Effect on Inverse Synthetic Aperture Radar

In order to resolve jamming effect evaluation about imaging radar,based on the concept of Mean Square Error(MSE),an evaluation technique of barrage jamming effect on Inverse Synthetic Aperture Radar(ISAR) has been proposed in this paper. Compared with former methods,it not only quantifies the evaluation of jamming effect from zero to one,namely,it is unitary,but also it has smaller amount of computation,so the jamming modes can quickly be evaluated. Two typical noise jamming modes are employed in computer simulation of interference with the raw ISAR data. The result shows the method proposed not only cuts computation amount but also has such advantages as unitary,objective,quantitative.
