| 摘 要： | 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.

| Abstract: | The recursion relation of radial distance among three stations can be derived after making applicable angle transformation for Doppler shift equation and making use of the correspondent transformation relation between coordinate variation and slide viewing angle.Furthermore, based on inherent geometric relationship, we can obtain the analysis formula of the radial distance between carrier aircraft and aeroplane carrier only according to the measured value of Doppler shift. Soon afterwards, the error analysi... |
