摘要
针对组合导航环境下的PN码捕获特点,采用分段并行捕获技术+多次最大值判决策略,解决了高动态、大多普勒频移下PN码快速捕获的工程实现问题。从理论分析和仿真结果看是切实可行的。
According to the characteris of PN code acquisition in integration navigation receiver, the paper brings forward a scheme of segment - code parallel acquisition and maxvalue judge for more time, which can solve the problems of PN code rapid acquisition in large dynamic range and doppler shift of the receiver. Theory analysis and simulation verified the validity of the methed.
