摘 要: 针对卫星终端分布式相控阵天线系统的传统时延估计方案存在的问题,研究了基于合成信号的多路时延估计方案,设计了简化方案的动态调整策略,仿真结果表明该方案能够有效地提升时延估计的性能,算法复杂度较低,同时添加动态策略的时延估计简化方案能较好地减小系统误差。 Aiming at the problems of the traditional estimation scheme of time delay in distributed phased array antenna system ofsatellite terminal, this paper studies the multi-channel delay estimation scheme based on the synthesized signal, and designs the dynamicadjustment strategy of the simplified scheme. The results of simulation show that this scheme can effectively improve the performance ofdelay estimation, reduce the complexity of algorithm. The simplified scheme of delay estimation of adding dynamic strategy can reducethe error of system.
