摘要 合成孔径雷达通过距离向的脉冲压缩技术和方位向的合成孔径天线实现距离维和方位维的高分辨率。文章在建立对点目标成像模型的基础上,引入SAR图像质量评估指标,用峰值旁瓣比和积分旁瓣比来定量地评价有源噪声压制干扰对点目标成像的干扰效果,并就几种典型的噪声压制干扰样式对SAR的干扰进行了计算机仿真。 SAR can achieve high resolution of distance and orientation by impulse compression technique in the distance and synthetic aperture antenna in the orientation. Based on the establishment of spot object imaging model, the evaluation guidelines of SAR image quality are introduced. The jamming effect of active noise suppression jamming to spot object imaging is evaluated quantitatively by using the ratio of peak value side lobe and the ratio of integral side lobe. Several typical noise suppression jamming models are simulated.
