摘　　要：研究了小波变换谱估计用于频率步进毫米波高分辨力雷达目标一维距离像的成像方法．选用已调高斯函数作为小波基函数，进行小波变换的信号功率谱估计，获得高质量的频率步进毫米波雷达目标的一维距离像．The application of wavelet transform to the 1 D target imaging of the step frequency MMW high definition radar was studied. The algorithm based on multirange cells was proposed using modulated Gaussian wavelet transform and good guality 1 D images of the radar target were obtained. The results indicate that the method is valuable for the improvement of target classification.
