摘要
对再生伪码测距中测距码的捕获方式和星上再生原理进行了仿真实现,利用simulink对再生伪码测距系统中测距码的捕获原理和星上再生原理进行了建模和分析,其中测距码捕获的判决方法以级联改进算法为主,同时对各个模块的功能进行了仿真,结果表明:再生伪码测距关键技术的设计可以有效实现测距码的捕获和再生,达到了预期效果,在深空测距应用中具有一定的实用价值。
The thesis carried out a simulation realization of the acquisition mode and the principle of regeneration on-board in the system of the regenerative pseudo noise ranging. Taking Simulink as the simulation tool,the principle of the acquisition of the ranging and the principle of the regeneration onboard were set up and analyzed,among them,the decision method of the acquisition of the ranging code was mainly based on the improved cascade algorithm,and the functions of each module were introduced in detail. The simulation can be known that the design of the key technologies of the regenerative pseudo noise ranging,can effectively achieve the acquisition and the regeneration of the ranging code,which achieved the desired effect and has certain practical value in the applications of the deep space ranging.
