| 摘 要： | 针对逆合成孔径雷达(ISAR)在成像上遇到的由于一维距离像随机平移造成成像效果变坏的问题,通过分析得出增加横向分辨率能够提高ISAR图像的信噪比这一结论,从而可以把随机平移对成像的影响视为噪声干扰,提高横向分辨率可以降低运动补偿精度要求的同时,还可以在做运动补偿成像后使目标像达到一定效果的情况下,放松对ISAR信号信噪比的要求。结果表明上述方法可行。

| Abstract: | This paper concerns the relationship between the cross sampling rate and the image SNR. According to the conclusion that the increment of the cross sampling rate can increase the SNR of the target image,the motion compensation accuracy requirement of ISAR can be reduced,and the SNR requirement of the signal before image processing can be reduced in order to obtain a specific target image SNR. The validity of the method is demonstrated by simulation. |
