數據採集系統採用鎖相技術、同步檢波的原理，降低了整個系統的成本，提高了靈敏度，並使得載波信號與調制信號完全達到同步。The performance targets of acquisition and tracking : the code rate of pseudorandom signals is 1m - 5mhz, the code length is 255. 511, the receiving sensitivity is - 118dbm, the dynamic range is 70db. the doppler of carrier is 75khz, the time that 10 targets are captured within 0. 2s
捕獲和跟蹤的性能指標：偽隨機信號碼率1m 5m比特/秒，碼長是255 、 511 ，接收靈敏度是- 118db ，信號動態范圍是70db載波普勒是75khz ，目標捕獲在0 . 2秒內。Satellite laser altimeter return waveform is sensitive to the vertical canopy structure and the change of underlying ground elevation. it is optimal for mapping forest structure. the return waveform and the processing method are described. the relationship between laser waveform and canopy structure parameters is explored ignoring the clumping effects. the clumping caused that structure parameters are different from the actual value. to solve this question, a model by 3 - d canopy structure parameters is needed
星載激光測高儀的回波信號能夠靈敏反映地面植被組成和地表高度的變化，因此能夠用於探測森林地貌;首先對星載激光測高儀的森林回波信號及其處理方法進行了介紹，探討了在不考慮植被聚集情況下，植被組成與回波信號之間的關系;由於植被的聚集效應，例如樹葉群集成樹冠，會導致植被組成參數與真實值之間存在差異，這需要建立關於三維的空間分佈模型加以解決。
