面向星载侦察载荷测试的场景模拟软件设计OA

With the rapid development of electronic reconnaissance technology,traditional testing methods struggle to meet the demands of dynamic simulation of emitter signals and closed-loop system testing.To address this issue,a scenario simulation software is designed for the testing of spaceborne reconnaissance payloads.A full-process simulation is realized,covering the transmission of radiation source signals,chan-nel propagation and reception by the satellite platform.By adjusting signal parameters such as time delay,frequency and phase,the radiation source signals intercepted by the payload in predefined scenarios are simulated.It is divided into 4 modules:parameter configuration,scenario simulation,data storage/retrieval,Satellite Tool Kit,and communication interface module.The simulation of multiple radiation sources using a single baseband source is achieved through techniques like pulse sorting and blanking.Additionally,methods such as time-shared multi-threaded generation and radiation source preprocessing are employed to address issues of excessive data volume and prolonged computation time.Finally,based on real-world application scenarios,the software is tested and subjected to performance analysis,confirm-ing that this software can be correctly operated,and demonstrating that there is a significant increase in computational speed and generating 6 million pulses requires 5 min.
