淺地層探地雷達(dá)合成孔徑處理的一種快速算法

A Fast SA Algorithm for Subsurface Penetrating Radar

  • 摘要: 該文根據(jù)淺地層探地雷達(dá)回波信噪比較高的特征,結(jié)合基于微波全息技術(shù)的SA(Synthetic Aperture)成像算法,提出了一種基于A掃描能量進(jìn)行自動(dòng)目標(biāo)方位識(shí)別、減少合成孔徑運(yùn)算量的快速算法.該算法簡(jiǎn)單、易實(shí)現(xiàn)。通過對(duì)實(shí)測(cè)數(shù)據(jù)進(jìn)行處理,所成圖像與普通合成孔徑算法成像基本相同,但速度有了極大地提高。
    Abstract: This paper presents a fast SA(Synthetic Aperture) algorithm based on the high SNR of the subsurface Subsurface Penetrating Radars (SPRs) 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.
