摘要
对舰船目标的合成孔径雷达(SAR)图像(复值)进行再处理,可以对舰船目标进行更精细的成像及轨道计算。开发这些算法需要大量的测试图像。但是由于实验条件的限制,这些图像的数目非常有限,因而研究舰船目标的SAR图像仿真就显得十分必要。提出了对舰船目标的SAR图像进行仿真的一种方案。首先通过仿真舰船目标的SAR成像过程以得到舰船目标的SAR图像,接着根据海杂波SAR图像的统计特性对海杂波的SAR图像进行仿真,最后将两者叠加以获得海面舰船目标的SAR图像。仿真结果显示了该方案的有效性。
A ship can be finely imaged and its trajectory can be calculated from its synthetic aperture radar （SAR） image. In order to develop these algorithms, people need a lot of test images. However, due to the difficulty in experimentation, the number of such images is limited. Therefore, it is necessary to study how to simulate the SAR images of ships. This paper proposes a scheme for simulating the SAR images of ships. First, the SAR imaging process is simulated to obtain the SAR images of the ships. Then, the SAR image of the sea clutter is simulated using its statistics. Finally, the two images are superposed to obtain the SAR image of the ships and the sea clutter. The simulation results show the effectiveness of this scheme.
