浅地层探地雷达合成孔径处理的一种快速算法

A Fast SA Algorithm for Subsurface Penetrating Radar

该文根据浅地层探地雷达回波信噪比较高的特征,结合基于微波全息技术的SA(Synthetic Aperture)成像算法,提出了一种基于A扫描能量进行自动目标方位识别、减少合成孔径运算量的快速算法.该算法简单、易实现。通过对实测数据进行处理,所成图像与普通合成孔径算法成像基本相同,但速度有了极大地提高。

This paper presents a fast SA(Synthetic Aperture) algorithm based on the high SNR of the subsurface Subsurface Penetrating Radar's (SPR's) reflecting signal and the SA algorithm of microwave holographic imaging. With this fast algorithm,the target azimuth is automatically detected and the amount of SA operating data is cut down. The algorithm is simple and easy to be realized. When the image is processed with the fast SA algorithm, the result is almost the same as the image processed with the general SA algorithm, but its processing speed is enhanced greatly.
