极化相控阵雷达单脉冲技术研究

Monopulse Technique of Polarization Phased Array Radar

针对极化相控阵雷达研究了单脉冲技术,提出了极化融合单脉冲算法和极化匹配单脉冲算法,可以同时测量目标角度与回波极化状态。通过仿真研究了两种算法的测角性能以及极化矢量估计性能。研究表明:两者测角性能和极化矢量估计性能几乎完全相同,测角性能与回波的极化状态无关,并且均优于单极化相控阵雷达。

The monopulse technique of polarization phased array radar has been investigated.Two monopulse algorithms termed by polarization fusion and polarization match are proposed,which can give the target angle and polarization state.Their performances have been contrasted with each other by simulations.It has shown that their performances are almost the same on angle measurement and polarization vector estimation.The root-mean square error of target angle is independent on the polarization state and lower than that of single polarization radar.
