摘　　要：时域平面近场散射测量是一种在近场区域进行散射测量的技术,可以有效地进行宽带的散射测量,具有超宽带测试、可以获得时域散射场、空间利用率高等特点.针对时域平面近场散射测量技术体系,在时域近场测量的理论基础上,提出了系统组建方案,论证了系统的可行性,开展了针对典型目标的验证测试,并对测量结果进行了初步的误差分析.证明了时域平面近场散射测量的有效性.Time domain planar near field scattering measurement is a direct and effective method.It has some advantages,such as wide frequency band,holonomic time domain scattering data,high space utilization and so on.In this paper,the technical architecture of time domain planar near field scattering measurement is illustrated.Based on the principle of time domain planar near field scattering measurement,the construction scheme of this measurement system is designed,and the feasibility is proved.The effectiveness of this system is proved by analyzing the actual measurement data and corresponding errors.
