摘要
在理论分析多径效应对高速运动被动雷达导引头对地定位精度影响的基础上,采用MATLAB进行了仿真分析,得到被动雷达导引头越接近目标物体,多径效应等对测向误差干扰越大的结论。此外,设计了一套半实物测试和验证方案,在室内环境下,建立了被动雷达导引头对地定位测试和验证的复杂无线信道环境。
Based on the theoretical analysis of the ground positioning accuracy with multipath effect, the result that positioning error casued by multipath interference would be greater when passive radar seeker is closer to target object is present. Finally, a semi-physical test and verification simulation scheme is present, and the complex wireless channel environment is established to test and validate ground positioning of passive radar seeker under laboratory conditions.
