In this thesis, a kind of 2 - dimention signal acquisition method is presented which combines parallel pn code phase and carrier frequency acquisition, as a result the acquisition time is shortened greatly. besides, according to the fact that the detection of spread spectrum signals is always the key point in the receiving system
在擴頻信號的捕獲過程中要求有較小的時延和較高的概率，本文介紹一種二維信號的捕獲方法，這種方法結合偽pn碼和載波頻率的獲取，捕獲時延將大幅度降低，實際上，擴頻信號的檢測是接收系統的關鍵。 -
The parallel computing ability of wave number domain algorithm is also being studied basically. the influence of the carrier movement errors on the sas image is analysed in chapter three firstly. based on studying those algorithms which have been successfully applied in sar, the limitations of these auto - focusing algorithms are discussed. hereafter an auto focusing algorithm based on time delay and phase error evaluation is raised, which can compensate big movement error effectively and so can be applied in sas
第三章首先分析了孔徑上運動誤差對合成孔徑聲吶圖像的影響，在研究在sar領域里成功應用的演算法的基礎上，對其運動補償的局限性做了分析，提出一種基於時延相位估計的自聚焦演算法，它能夠有效地補償運動誤差帶來的影響，並且適用於sas運動誤差較大的情況。
