Spaceborne phased array radar load with thermal control integration with satellite platform structure

Abstract

The present invention relates to a spaceborne phased array radar load with thermal control integration with a satellite platform structure. The spaceborne phased array radar load is integrated on a satellite deck and comprises a phased array antenna, an active module and a thermal control device. The phased array antenna covers on an outer side surface of the satellite deck; the active module ismounted on an inner side surface of the satellite deck and is arranged corresponding to the phased array antenna; the thermal control device is embedded in the satellite deck and is arranged between the active module and the phased array antenna; and the active module is connected with the phased array antenna to implement microwave signal transmission. According to the spaceborne phased array radar load provided by the present invention, the spaceborne phased array radar load and the satellite platform share one satellite deck, and the thermal control device is integrated into the inside of the satellite deck, so that thermal control integration between the spaceborne phased array radar load and the satellite platform structure can be achieved, the integration is high, the space occupation is small, and the overall weight is reduced.

Description

technical field [0001] The invention relates to a space-borne radar structure, in particular to a space-borne phased array radar load integrated with a satellite platform structure thermal control. Background technique [0002] The spaceborne phased array radar mainly consists of two parts, the phased array antenna and the central electronic equipment, and generally adopts a configuration design independent of the satellite platform. Phased array antennas are usually in a self-contained planar configuration. According to the satellite configuration and the envelope size of the entire rocket cover, the antenna aperture is divided into several panels. Each panel contains: phased array antenna, antenna frame, active mounting plate, thermal control device, cables and active modules. Antenna panels and satellites are generally heat-insulated. When working in orbit, the antenna panel solves the thermal control problem of the heating device by itself; the central electronic equi...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing phased array antenna, satellite deck and thermal control device are all independent parts, and each part is independent of each other when connected, and there are many installation paths, resulting in large space occupation, poor heat dissipation effect, Heavy weight and low integration
