In this dissertation, we systematically study the pulse - position - modulated pulse - sequence ( ppm - ps ) radar signal theory and its applications to radar / fuze systems
本文系統地研究了脈位調制脈沖串雷達信號理論及其在雷達引信中的應用。 -
A new pattern position sensitive detector is introduced, so the accelerometer has many advantages including high sensitivity, high resolution and quick response speed. a binary width - modulated pulse rebalance loop is applied in the accelerometer
該加速度計引入了新型位置敏感探測器psd ，使其具有高的靈敏度、解析度和響應速度;同時採取了二元調寬脈沖加矩方式的再平衡迴路。 -
In this paper they study a position - detecting system based on microprocessor and psd ( position sensitive detector ). the method is as follows : when the ac - signal from psd which is illuminated by modulated light source passes through an active band - pass analog filter, it filters the ac signal which represents the object light source. then the dc - converter circuit transforms it into dc - signal which is used to calculate the position
這一系統採用的方法是通過對位置敏感探測器psd受到調制目標光源照射后輸出的模擬交流信號進行有源帶通濾波，提取出代表目標光源的調制頻率成份，再將該信號轉變為用來參與位置解算的直流信號，然後選用單片機組成硬體電路，對直流信號進行採集處理並與計算機建立通信，把數據送入計算機進行位置解算，分析判別目標光源和psd器件的相對位置。
