通过对多普勒频移方程进行角度变换,并利用在下滑视角和坐标变量之间的对应关系导出了在三个站点的径向距离之间的递推关系。在此基础上,进一步利用固有的几何关系,即能由任一瞬间所测得的多普勒频移值,得到舰载机-航母之间径向距离的解析解。随后进行的误差分析表明基于多普勒频移测距可以实现分米级的测量精度。 By recursively transforming the Doppler frequency shift equation and using the correspondence between the downswing angle and the coordinate variables, the recursion relationship between the radial distances of the three stations is derived. On this basis, we further utilize the inherent geometric relationship, that is, the analytic solution of the radial distance between aircraft carrier and aircraft carrier can be obtained from the Doppler shift value measured at any moment. Subsequent error analysis shows that Doppler-based measurement accuracy can be achieved based on Doppler frequency shift ranging.
