基于Simulink的箔条走廊干扰仿真系统

The Simulink-based simulation system of chaff corridor jamming

采用Simulink仿真技术,对箔条走廊干扰过程和干扰效果进行了动态的信号级仿真。进行了作战场景想定,建立了箔条走廊对雷达干扰的模型体系结构,给出了仿真模块框图。给出了箔条走廊干扰的原理及数学模型,对仿真结果进行了对比分析。仿真结果表明,箔条走廊散射杂波可以压制常规脉冲雷达,箔条走廊对电磁波的衰减可以使MTD体制雷达接收不到目标回波。

Based on the Simulink simulation technology, the dynamic signal simulation is made for the process and effects of the chaff corridor jamming. With the battle scenes assumed, the model system structure of the chaff corridor jamming is established, and the block diagram of simulated modules as well as the principle and the mathematic models are also given. The simulation results are compared and analyzed to indicate that the scattering clutters of the chaff corridor can suppress conventional pulse radars, and the attenuation of the EMWs due to the chaff jamming enables MTD radars not to receive target echoes.
