半主动式导弹低空多路径效应的计算

对于半主动式多普勒导弹低空多路径效应给出了一个完整的仿真模型 ,它包括雷达天线模型、地面散射模型和目标模型三大部分 ,针对不同的目标航迹、导弹航迹和地物类型 ,通过它们的几何关系和散射关系结合起来。其中最重要的是地面散射模型 ,本模型可对低空目标的多路径效应进行功率计算。如果给定天线的有关参数 ,还可以对测角误差进行预估。最后给出了一些具体结果。

The Calculation of Multipath Effect for Semi-Active Radar Homing Missile

This paper a complete simulation model for target tracking of semiactive radar homing Doppler missile radar that works at low elevation angles with ground reflection multipath. It includes radar antenna model, ground scattering model and target RCS model all of which are integrated through their geometric relation and scattering relation according to different target trajectory, different missile trajectory and different kind of ground. In the simulation models, the ground scattering model is the dominating part which can be used to calculate the power of multipath effect and the angle error if some certain antenna parameters are offered. At last some figure results are provided.;
