Embodiment Construction
[0036] The inventive method comprises the following steps:
[0037] ①. Preparatory conditions: The object S is moving over the ground station, the observation surface is infinite, and the atmospheric wind field plane over the ground station is parallel to the observation surface;
[0038] ②, such as figure 1 As shown, establish a horizontal coordinate system: select an observation point L on the ground station and set it as the origin, and establish a horizontal coordinate system ,That The axis is horizontal to the east, The axis is horizontal to the north, axis vertically upward;
[0039] in the horizontal coordinate system middle, The surface is named as the observation surface, M is a point on the propagation path of the LS beam, and the height from the observation plane is , M' is the projection of M on the observation surface, S' is the projection of S on the observation surface, the state parameters of point S at a certain moment: the veloci...
