    概述了接收機的設計原理;詳細描述了基於ti公司的tms320c6713dsp晶元的系統程序設計中各模塊的實現,利用該晶元的資,實現各模塊的調度,完成對導航文的提取,重新組幀,定位解算以及對外介面;在解算,把載波相位定位與碼定位相結合,利用載波相位對偽的平滑來提高定位精度;在matlab平臺下進行了各模塊的功能模擬試,以模擬結果的圖表來析說明了載波相位平滑偽的兩種演算法能使定位精度有一定的提高。
  2. With the increasing requirements for detecting distance, photoelectric module, including light source and modulation, can be put under water to reduce the loss of light power in the optical fiber transmission and transmit the detected signal to the signal processing workstation on the shore. optical transceivers must be applied to realize the low - rate optical communication between the workstation on the shore and the long - distance photoelectric modules under water

    隨著光纖水聽器陣列技術的發展,可將光與調制作為遠程光模塊置於水下,減少光纖傳輸過程中光波信號的損耗,而直接將光纖的探信號傳回岸基工作站進行處理,以增加光纖水聽器的探離。
  3. In the first part of this paper, the theory of laser range and dds technology was introduced, the factors of influencing range precision were also analysed. at the same time, put forward in the paper, with using the fpga embedded technology, the wideband and high resolution sin modulating signals can be generated easily, then analysed the noise of the dds ; in the second part, the theory of phase measurement based on fft was analysed. in the phase range system, by using the fft operation, the resolution and sensibility of phase measurement can be enhanced ; then some circuits were designed and come true, also simulated and validated ; in last part, the improvement of the phase range system was brought forward, summarized and expected
