摘要
提出了一种适用于伪码测距雷达的伪码跟踪环设计方法,重点对伪码跟踪环的跟踪精度和动态性能进行了分析,讨论了一种最小跟踪误差意义下的最优环路带宽确定方法。仿真结果表明伪码跟踪环跟踪精度高,对动态运动的适应能力强。
This paper presents a PN-code tracking loop design in a PN-code ranging radar,and focuses on analysis of tracking accuracy and dynamic performance of the PN-code tracking loop.A computation method of optimal bandwidth according to the least tracking error is proposed.The results of simulation verify that the PN-code tracking loop has high tracking accuracy,and has good adaptability to target s movement dynamic as well.
