摘要
米波雷达在对抗现代隐身技术和ARM威胁等方面有其特有的优势,但多径效应使米波天线方向图发生畸变,严重影响其探测性能。针对多径效应对米波天线方向图性能影响进行了详细分析,给出了计算模型及仿真实例。最后,提出了改善多径影响的一些方法和途径。
Meter- wave radar has its unique advantage against modern stealth technologies and ARM threat, but multipath effect makes the antenna pattern of meter -wave radar be distorted which seriously influences its detection performance. In this paper, this kind of influence is analyzed in detail, the corre- sponding calculation model and simulation instances are given. Finally, some methods and solution are proposed to reduce the influence of muhipath effect.
