Embodiment Construction
[0030] (1) Calculate the ground speed vector according to the principle of kinematics;
[0031] According to the fact that the relative velocity is equal to the absolute velocity minus the implicated velocity, in general, the velocity of the imaging point relative to the satellite can be calculated by the following formula:
[0032] v 地 = ω e ×R-(v s +ω b ×H) (1)
[0033] where ω e is the earth angular velocity vector, R is the vector from the center of the earth to the imaging point, v s is the satellite velocity vector, ω b is the angular velocity vector of the satellite body coordinate system, and H is the distance vector from the satellite to the imaging point.
[0034] The ground speed is defined as the speed of the satellite relative to the imaging point, and we have
[0035] v 地 =-ω e ×R+(v s +ω b ×H) (2)
[0036] (2) Construct a vector triangle composed of several related velocity vectors, and judge the projected component direction of the ground speed on ...
