| 摘 要： | 外场RCS测量是获取大型全尺寸目标电磁散射特性的重要手段。在介绍脉间频率步进雷达一维、二维成像原理的基础上,给出了一种宽带(2～18GHz)双通道雷达目标RCS测量系统的设计与实现。该系统可用于外场目标后向电磁散射特性测量和散射源高分辨力二维成像。介绍了系统的技术特点,讨论了影响外场RCS测量精度的几种主要误差来源并提出了解决办法,最后对系统性能进行了验证。

| Abstract: | Outdoor RCS measurement is the principal means to obtain the RCS of a full-scale target.This paper firstly introduces the imaging principle of the pulse-pulse stepped-frequency radar.The design and implementation of a wide-band(2 GHz-18 GHz),two-channel RCS measurement system is described.This system can be applied to outdoor static backscatter RCS measurement of the full-scale target based on turntable,and the high-resolution 2-D imaging of the scatter sources.The technical features of the system are intro... |
