摘要
极化阵列雷达兼具阵列雷达的优势和极化信息处理能力,是当前先进体制雷达研究的热点。研究了极化阵列雷达单脉冲测角的问题。在明确雷达采用的天线结构的基础上,建立了极化阵列雷达接收信号模型,提出了基于极化并联的单脉冲测角方法,分析了该方法测角性能,给出了测角性能与SNR及回波极化角的关系。通过仿真验证了方法的有效性,研究表明:极化阵列雷达单脉冲测角性能优于任意单(同)极化阵列雷达,且测角性能与回波极化状态无关。
Polarization array radar is a new advanced radar system,which has many advantages and ca-pability of polarization information processing.Monopulse angle measurement method in polarization array radar has been studied.The receiving signal model has been established and a monopulse angle measurement method based on polarization parallel is proposed.The performance of the method has been analysed,inclu-ding the relation between performance and polarization angle.Simulation and theoretical analysis show that this method has an advantage of arbitrary single polarization array radar and performance of angle measure-ment is unrelated to echo polarization.It may be applied to polarization array radar.
