Differing form conventional approach, which regards the lateral acceleration of missile guidance as control command, this law adopts directly flight-path angle as control variable.
与导弹导引侧向加速度作控制指令的常规方法不同,该控制律直接采用航迹角作控制变量,即借助拦截末端的几何关系获得末端视线角,末端视线角与当前航迹角的误差作为控制量,实现导引控制。
The fact,that the flight-path angle of a satellite is not equal to zero in elliptic orbits,is neglected in the deduction processes of the existing formulae that are used to compute the Doppler parameters for spaceborne SAR.
国内外已有文献在推导星载SAR多普勒参数计算公式的过程中,均未考虑椭圆轨道下卫星航迹角不为零的影响,这使得已有公式只能近似地使用在近圆轨道上。
