摘要
应用角度变化率的概念,通过对多普勒频移方程施加微分变换,给出了仅基于频差测量的多普勒变化率近似计算式。随后,基于连续多点探测的方式,利用相邻探测节点间多普勒变化率和切向速度的比值关系,由速度恒等式即可获得多普勒实时测距公式,随后再次利用多普勒变化率方程式即能直接解得目标的相对方位。
Utilizing the conception of angle rate, the approximate calculation formula of Doppler rate only based on the measure of frequency difference can be obtained by applied the differential transformation to Doppler shift equation. Thus, based on the mode of continuous multipoint detection, using the ratio relationship between the Doppler rate and the tangential velocity, the real time ranging formula can be obtained by velocity identical relation between neighbor nodes. Hereafter, again using Doppler rate equation can directly solve the relative azimuth of target.
