The thesis reviews the theory which is the basis of synthetic aperture processing and introduces five algorithms of image reconstruction : the coherent addition provides a good opportunity for the real time sas ; the envelope processing can work when sonar echo returns lack phase coherence ; the i - q processing can reduce the sampling rate ; the broadband and ctfm processing are both aimed to increase the sas mapping rate
討論了用於重構圖象的五種演算法，包括簡單的可進行實時處理的相關合成法，可以在缺乏相位信息時使用的包絡處理法，可以降低采樣率、減少運算量、存儲量的正交處理法，可以提高聲納運行速度，從而提高成象率的寬帶處理法和ctfm法等五種演算法。 -
