一种星载雷达上注系统的设计与实现OA

In order to address the potential hazards of single-particle events(SPE)in the spaceborne environ-ments,achieve the functional upgrade and defect repair of the spaceborne radar system on orbit,and enhance its long-term operational reliability,a spaceborne radar upload system has been designed and implemented.Based on a microcontroller unit(MCU)and through dual-redundant upload channels and PROM/FLASH dual-redundant storage design,the software upload of the spaceborne radar system is achieved.The test results show that this sys-tem realizes the remote reliable upload and update of executable programs and configuration parameters of space-borne radar software,effectively resisting space environment interferences such as SPE,and enhancing the on-or-bit maintainability and operational safety of the spaceborne radar.
