| 摘 要： | 在机载探测平台匀速直线飞行的条件下,基于目标与测站间斜距和相位的变化关系,综合应用速度恒等关系和多普勒频移及其变化率方程,由前一时刻的径向距离、多普勒频移及变化率等参数,递推出当前时刻的多普勒频移值.Matlab软件模拟计算结果验证了所导出的测算式的准确性.

| Abstract: | On condition that airborne acquisition tracking system is uniform flight alone linear motion,based on the variation relationship between distance and phase,the current Doppler shift can be derived from foregoing moment information by compositely applying the velocity vector equation and the Doppler shift equation as well as the Doppler changing rate equation.The results of analog calculation by Matlab software verify that the derived formula is accurate. |
