Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like figure 1 As shown, a radar antenna alignment and tracking control method under a dynamic platform includes the following steps:

[0017] Step 1: The main control computer receives the carrier attitude data output by GPS and attitude measurement equipment through the RS232 or RS422 serial port, and receives the GPS coordinate value of the tracking target through the network port;

[0018] Step 2: The main control computer calculates the azimuth tracking command angle and the pitch tracking command angle through coordinate conversion, and sends them to the azimuth servo control board and the pitch servo control board respectively through the RS232 serial port;

[0019] Step 3: The resolver installed on the servo motor provides the current position of the turntable and feeds it back to the servo control board; the servo control board decodes the feedback sign...

Abstract

The invention discloses a radar antenna alignment tracking control method under a dynamic platform. The method comprises: receiving GPS, and the carrier attitude data output from an attitude measuring device by means of a main control computer, and receiving a GPS coordinate figure of a tracking target through a network port; through coordinate transformation, calculating an orientation tracking instruction angle and a pitching tracking instruction angle, continuously comparing the orientation tracking instruction angle with the current orientation rotary table position parameter by an orientation servo control panel, and controlling an orientation servo motor to change the position of the orientation rotary table on an antenna; and continuously comparing the pitching tracking instruction angle with the current pitching rotary table position parameter by a pitching servo control panel, and controlling a pitching servo motor to change the position of the pitching rotary table on the antenna. By means of the combination of the stabilization function of a servo-actuated stabilized platform with the servo control function of the radar antenna, the radar antenna alignment tracking control method under a dynamic platform can realize the influence of effective isolation of the attitude change of a carrier on direction of the radar antenna so as to realize direction stability of the radar antenna.

Description

technical field [0001] The invention relates to a radar antenna alignment and tracking control method under a dynamic platform, belonging to the technical field of automatic alignment and tracking control of ship-borne or vehicle-mounted radar antennas. Background technique [0002] The radar antenna automatic alignment and tracking control system is an important part of the radar. By driving the antenna to rotate, the radar antenna can be stably pointed or automatically track a target in the airspace. Therefore, the performance of the automatic alignment and tracking control system directly determines the overall performance of the radar. [0003] Under dynamic platforms such as ship-borne or vehicle-mounted, the antenna will shake due to the dynamic change of the carrier attitude. At this time, some compensation measures are required to effectively isolate the attitude change of the dynamic carrier and achieve the purpose of stabilizing the pointing. [0004] At present, ...
