Total dose reinforcement resistant optimization calculation method and system applied to high-orbit satellite

Abstract

The invention provides an anti-total dose reinforcement optimization calculation method and system applied to a high-orbit satellite, relates to the technical field of satellite anti-radiation design, and aims to construct an efficiency-cost ratio optimization model for satellite anti-total dose reinforcement for a high-efficiency cost ratio. According to the model, an anti-total dose design margin (RDM) is used as an evaluation index, quality grades and anti-total dose capabilities of different types of satellite components are used as core parameters, and a parameter model of anti-total dose reinforcement cost, component grades and shielding quality is established. Then, the cost-effectiveness ratio serves as a target function, a gradient-based optimization method is adopted, optimization design is conducted on satellite total dose reinforcement resistance, and uncertainty in the optimization process is analyzed and discussed. The method is high in operability and realizability, the on-orbit reliability of a satellite system can be improved on the premise that the requirements for the service life of the satellite and the total dose reinforcement resistance are met, and the development cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of satellite anti-radiation design, in particular to an anti-total dose reinforcement optimization calculation method and system applied to high-orbit satellites. Background technique [0002] The new generation of scientific satellites, including Jupiter detection, faint target detection satellites, and high-resolution photoelectric detection satellites, are all moving towards high-resolution, high-sensitivity, hyperspectral, all-weather, and all-time. space area. However, there are a large number of high-energy protons, electrons, cosmic rays, and auroral radiation in outer space, which can easily cause radiation damage to high-precision, high-resolution, and high-sensitivity detection payloads and components, and affect satellite detection tasks. [0003] The design of satellite anti-total dose reinforcement is one of the key directions of space protection design. The previous design work relied too much...
