摘　　要：当前对飞行器平台射频隐身的重视度越来越高,为了贴合实际地分析评估射频隐身性能,提出了一种用于多机协同传感器信号级联合仿真的评估方法。结合射频特征、低被截获性能表征指标以及作战场景、飞行器平台、雷达模型、截获接收机模型和低被截获性能分析算法模型,构建了可以用来对多机协同等作战样式下的射频隐身性能进行分析评估的仿真系统,为射频隐身设计提供支撑依据与评估验证环境。针对信息量大、复杂度高的表征参量计算模型,研究其近似快速算法,提高仿真系统的实用性。Currently,more and more attention is paid to the radio frequency(RF)stealth of aircraft platform.In order to analyze and evaluate the RF stealth practically,an evaluation method for signal level simulation of multi-aircraft sensor collaboration is proposed.Combining the performance characterization indicators of RF characteristics and low probability of intercept(LPI),and the entity including combat scenarios,aircraft platforms,radar model,interception receiving model and LPI performance analysis algorithm model,a simulation system is built to conduct simulation analysis and evaluation of radar RF LPI performance under multi-aircraft cooperation and other combat styles.The system can provide supporting basis and evaluate validation environment for aircraft radar RF stealth design.In view of the characterization parameter calculation models with large computational operations and high complexity,the research on approximate fast algorithms for simulation model is conduct to improve the practicality of simulation system..
