一种机载雷达信号级实时半实物仿真重演系统设计OA

In order to solve the problem of poor real-time performance and low fidelity of clutter simulation in airborne radar,a design scheme of real-time signal-level simulation replay system developed based on real ra-dar equipment is proposed.This scheme can be used to superimpose fine real-time simulation targets and interfer-ence signals on the playback of the recorders'real flight echoes,and to adjust key signal and data processing pa-rameters online,realizing high-fidelity real-time signal-level simulation replay.It also can be used for daily exer-cise and training,operational research,radar performance verification and improvement,etc.with the characteris-tics of high replay efficiency and wide coverage.In addition,the software interfaces and communication methods are highly compatible with actual equipment,and the development efficiency is high and the stability is good.
