现代机载火控有源相控阵雷达对数据处理的要求越来越高,雷达软件的复杂度越来越大。雷达系统对软件功能验 证和算法优化的要求也越来越高,因此针对机载相控阵火控雷达软件研发的需求,建立一套可应用软件系统开发和测试 的分布式半实物仿真系统必不可少。文中讨论了该系统的组成和工作流程,提出了一套有效实用的目标、载机运动轨迹 仿真模型和雷达回波产生模型。该仿真系统在机载相控阵火控雷达系统软件的开发过程中得到成功验证。

Modern airborne active phased array fire-control radar calls for increasingly high data process capability, the radar software has become increasingly complicated. Radar system also demand more and more requirement on software function verification and algorithm improvement, therefore , it is necessary to establish the a distributed hardware-in-the-loop simulation system which can hold the whole software lifecycle to satisfy the requirement of airborne phased array fire-control radar software development. In this paper, the structure and operating process of the simulation system are discussed. The method to simulate the tracks of target and carrier, as well as radar echo is proposed . The related simulation method and software system has been validated successfully in the practical software system of airborne phased-array fire control radar.
