Abstract

The invention discloses a space-borne complex radar antenna high-rigidity biased-type fixed direction pointing mechanism, comprising: an active unfolding locking mechanism, an extension arm, a two-dimensional servo mechanism, a pressing releasing mechanism, and a floating bracket. The pressing releasing mechanism comprises a pressing cup, a supporting component, a pressing rod, a pressing head cover and a vibration damping head cover. The invention provides an effective solution for the installing and fixing of a space-borne complex radar antenna and the tracking and positioning of an in-orbit target. The mechanism has the advantages of small size in envelope, high rigidity in structure and convenience in installation.

Description

technical field [0001] The invention relates to the field of aerospace electromechanical technology, in particular to a high-rigidity offset fixed pointing mechanism for a space-borne complex radar antenna. technical background [0002] One of the core components of the antenna pointing mechanism radar system is the actuator for the radar antenna to track and orient the target. With the continuous expansion of the radar functions of modern spacecraft, the radar antenna has developed from a flat plate antenna with a diameter of less than half a meter to a parabolic antenna with a diameter of more than 2 meters. Therefore, the radar antenna is folded and pressed tightly on the side of the satellite to meet the requirements of the envelope and mechanical conditions during the satellite launch phase. After entering orbit, it is lifted to a position away from the side plate of the satellite and then the target is tracked and positioned. [0003] With the continuous increase of r...
