Design method for power supply and distribution system of high-power phased-array antenna of polar orbit satellite

Abstract

The invention provides a design method for a power supply and distribution system of a high-power phased-array antenna of a polar orbit satellite. The design method comprises the following steps: determining to use a non-adjustable high-voltage double-bus power supply according to requirements of power of over ten thousands of watts of the phased-array antenna and features of a polar orbit; designing a solar battery array; determining the working voltage of the solar battery array to be about 70 V according to the features of the polar orbit; enabling open-circuit voltage to exceed 80 V; and taking anti-static precautions and the like. The problem that generation and control of high-voltage large current required for the high-power phased-array antenna of the polar orbit satellite and severe control of a charging sequence of the phased-array antenna are difficult is solved, hidden dangers of single location invalidation in the design of antenna single-bus power supply are eliminated, model selection difficulty and the like of circuit switch elements of power distribution control units of antenna buses are reduced, and reliability and safety of operation of the power supply and distribution system of the phased-array radar antenna of the satellite are greatly improved.

Description

technical field [0001] The invention relates to an aerospace power supply and distribution system method, in particular to a design method for a polar-orbit satellite high-power phased array antenna power supply and distribution system method. Background technique [0002] Synthetic Aperture Radar Satellite is an active remote sensor working in the microwave band. It is not affected by factors such as sunshine and weather conditions, and can observe and image the earth all day and all day long. It has unique application advantages in disaster monitoring, environmental and ocean monitoring, resource exploration, crop yield estimation, surveying and mapping, and military affairs. The irreplaceable role of remote sensors. In order to ensure the space-borne SAR system's ground-visible observation bandwidth and imaging performance, the general space-borne SAR antenna will use a large planar phased array antenna. The planar phased array antenna has the advantages of high transmi...
