摘要
在对相位差变化率定位技术原理和现有单站无源定位方法进行对比分析的基础上,具体介绍了基于相位差变化率的单站无源定位方法,并对相位差变化率单站无源定位与跟踪的一些关键问题进行了研究分析.在保证跟踪精度的前提下,提出了一种限定相位差变化率的单站无源定位方法,推出了其定位公式和定位精度公式,并通过计算机仿真验证了该方法的有效性.
Base on the principle of phase rate of change and the method of existing single passive location system have been introduced and analyzed,the method of a single observer based on phase difference rate of change has discussed,and the related key techniques with the method are mainly discussed.On the assumption that the tracking accuracy can be ensured,an improved method with restrict phase rate of change has been bring forward,formulae of location and accuracy are presented.Simulations show that this method is effective.
