相控阵靶标雷达模拟新方法

Novel Technique of Phased Array Target Radar Simulation

提出一种模拟相控阵靶标雷达的新方法.用机械扫描雷达模拟相控阵雷达天线的主瓣电磁辐射特性;用喇叭天线阵列雷达模拟相控阵雷达天线副瓣电磁辐射特性;通过控制机械扫描雷达和喇叭天线阵列雷达的发射机分时交替发射,模拟相控阵雷达在空间的主、副瓣交替扫描特性.仿真结果表明,该方法可以逼真地模拟相控阵雷达天线电磁辐射特性,同时极大地降低相控阵靶标雷达的研制、使用、维护成本,加快研制周期.

A novel simulation technique of phased array target radar is introduced.Mechanical scanning radar is used to simulate the main-lobe fluctuation property of phased array radar,and trumpet array radar is used to simulate the side-lobe fluctuation property.By the time-sharing work of transmitters of mechanical scanning radar and trumpet radar array,the alternant radiation property of main lobe and side lobe in the space is simulated.This method realizes the realistic simulation of electromagnetic fluctuation property of phased array radar,and of the same time,the fabrication and maintenance cost is saved and the development period is shortened.
