  1. Considering the fact that the analog system is not so good as the digital system on the respect of variation of bandwidths and on the respect of switch between different bandwidths. this paper proposes to adopt the dds ( direct digital synthesis ) technique that produces chirp signals of different bandwidths to improve the situation of losing tracks for the ocean satellite altitude indicator in measuring coarse surfaces

    現在的雷達基本上採用模擬系統產生線性調頻信號，由於模擬系統在帶寬變化方面和不同帶寬間切換方面不如數字系統，本文採用dds （ directdigitalsynthesis ）技術產生不同帶寬的線性調頻信號以改善海洋衛星高度計在測量粗糙表面時存在的失鎖現象。
