Abstract

In this paper, we develop a single-position method of passive location and navigation with allowance for the periodicity of the radiated radio signal (the period may not be known) when one of the objects in the radiation source–observer pair is stationary and the second moves along a piecewise linear trajectory with an unknown velocity. The measured parameter is the time difference between the periods of the emitted and received radio signals. The issues related to the estimation of the Doppler frequency corrections based on this discrepancy, to the observability of the method for different special cases, the estimate of its accuracy characteristics, and practical recommendations are considered. A numerical example is given.

允许接收点无线电信号周期演变的单位置无源定位和导航

摘要

在本文中，我们开发了一种无源定位和导航的单位置方法，并考虑到辐射源 - 观察者对中的一个物体静止且辐射无线电信号的周期性（周期可能未知）。第二个以未知速度沿分段线性轨迹移动。测量参数是发射和接收无线电信号周期之间的时间差。考虑了与基于这种差异的多普勒频率校正估计、该方法在不同特殊情况下的可观察性、其精度特性的估计以及实际建议相关的问题。给出了一个数值例子。
