引入以自适应数字滤波器模拟空间信道传输特性的概念,讨论了提高甚低频方位距离导航系统中方位信号的检测精度的问题,对利用两条方位线定位的导航系统的坐标变换提出了新的处理方法.本文还介绍了在TRS—80微型机上模拟该系统定位过程的结果.
This paper introduces the concept of adaptive digital filter to simulate the transmission characteristics of spatial channels, discusses the problem of improving the detection accuracy of bearing signals in navigation systems with very low frequency range, and proposes a new coordinate transformation of the navigation system using two azimuth lines This article also describes the results of simulating the positioning of the system on a TRS-80 microcomputer.
