摘要:
该文针对星基定位接收机导航信号捕获的干扰问题，提出一种非完备空际间叠干扰信号模型。首先对提出的干扰模型以及非完备空际间叠引起的干扰裂变效应进行了阐述分析与推究证明，而后推导计算出了星基定位接收机输出信干噪比(SINR)与空际间叠长度的函数式，论证了两者函数单调性关系。仿真实验表明星基定位接收机输出信干噪比为空际间叠长度的单调增函数，短空际间叠长度干扰可抑制3维频码域相关峰突起，降消星基定位接收机捕获性能。
Abstract:A non-complete spatial overlapped interference signal model is proposed based on the jamming research against satellite-based positioning receiver for the acquisition of navigation signal. Firstly, the interference model is introduced and analyzed, and the signal fission effect induced by non-complete spatial overlapped interference is demonstrated. Then, the relationship between SINR of satellite-based positioning receiver and spatial overlapped length is derived, and the monotonic relationship of them is deduced. Simulation results suggest that SINR of satellite-based positioning receiver is the monotonically increasing function of spatial overlapped length, and the short-spatial-overlapped interference can restrain the peak amplitude of three dimensional frequency and coded domain correlation, degrading the performance of acquisition of satellite-based positioning receiver.
