Echo Simulator Design for New Generation Airborne Fire-Control LPI Radar

低截获概率(LPI)雷达是未来空战的必然选择,其波形设计及有效性验证是LPI技术的核心内容。针对新一代机载火控LPI雷达,产生了几种典型的具有低截获性能的雷达波形,并对其回波信号进行计算机仿真,包括波形的产生、目标回波、环境杂波的建模与仿真等。该雷达回波模拟器可根据上位机的指令,灵活设置雷达回波的各种参数,满足不同背景下LPI雷达回波信号仿真建模与计算机模拟的需求,对于雷达波形的LPI性能评估具有实用性。

Low Probability of Intercept （LPI） radar is the inevitable choice of aerial wars in the future, with its waveform design and validity test as the key contents. This paper deals with simulation of radar echo signal about the new generation of airborne fire control LPI radar,including LPI radar waveform design and radar echo signal simulation technology which contains the simulation of target echo and the environmental clutter and so on. The radar echo simulator designed here can enable users to select and set waveforms and parameters flexibly according to various situations,tiros meeting the demands of LPI radar echo signal simulation modeling and computer simulation in different echo situations. It can also be applied to testify the validity of the performance about LPI radar waveform and signal processers,which has great practical value.
