Abstract

The invention discloses a computer of integrated satellite-borne SAR loads. The computer comprises a main control module, a telemetry and telecommand module, an interface expanding module, a power module and a backboard. The main control module is used for data processing, timed controlling and wave beam controlling; the telemetry and telecommand module is used for receiving a satellite platform instruction, analyzing the instruction to all single units of the load system to instruct production and OC gate control, and collecting the temperature, voltage analog quantity and the digital quantity telecommand signal of the load system; the interface expanding module has the functions of communication management and interface expanding; the backboard is used for power supply and signal connection of the main control module, the interface expanding module, the power module and the telemetry and telecommand module. Through integrated design of functions of time sequence control, wave beam control, and interface control when the SAR loads work and the telemetry and telecommand of all single units of the load system, the integration level and the reliability of the SAR system are improved,the weight, size and the power dissipation are lowered, data transmission among all machines of the SAR load system is reduced, and the reliability of the SAR load system is improved.

Description

technical field [0001] The invention relates to the technical field of spaceborne computers, in particular to an integrated spaceborne SAR payload computer. Background technique [0002] Traditional SAR center computer wave control and system timing control adopt distributed design, generally composed of a fixed controller, wave controller, digital tube computer and other stand-alone machines. With the increase of SAR payload task functions, the communication connection between each stand-alone machine is complex and requires high real-time performance, which requires a dedicated high-speed internal bus connection. The power supply loss and command control of these functional units also occupy a certain amount of repetitive resources, resulting in excessive volume and weight of the entire system, serious waste of resources and energy consumption, and even affecting the communication stability between functional units. Performance and reliability are affected to some extent....
