摘要
针对传统的PD(pulse Doppler)雷达测量分辨率低,在多目标识别方面存在缺陷,讨论一种在多目标检测中基于六端口技术的雷达体制.分析表明,在传统的信号检测基础上,利用六端口精确的相位测量能力,能够有效提高速度分辨率和距离精度.计算机仿真说明,基于六端口技术的双频PD雷达体制在解决多目标检测中是行之有效的.
The traditional pulse Doppler （PD） radar has its own limitation in multi-target detection. Dual frequency PD radar based on six-port technology was proposed to solve this problem because of its phase measurement capability. The method of using six-port radar to detect multiple-targets＇ range/relative velocity is discussed and computer simulations prove that the method is valid and practical.
