摘　　要：分析和对比了两种常用的HRR脉间变频外场RCS测试设备的设计方法,针对脉间变频格式RCS测试一维成像的特点提出了一种简化设计的思路。由于快速跳频源制造技术的进步,通过适当调整系统的设计参数,将原来所采用的正交解调硬件结构简化为单通道的处理结构,而系统的测试能力没有受到影响。该简化设计能够减少大约30%的微波元器件,降低了成本,精简了结构。最后给出了该设计的外场测试结果,并对测试结果进行了分析。Two usual designs of High-Range-Resolution pulse to pulse frequency shifting RCS outdoor measurement device are analyzed and compared. A simplified design is presented point to the peculiarity of the pulse to pulse frequency shifting RCS measurement One-Dimension imaging. The design parameters of the measurement device are properly adjusted due to the development of fast-frequency-shifting sources. The quadrature demodulation architecture is replaced by single-channel architecture without reducing the system’s measurement capability. This design can economize the microwave components about 30% and simplify the system’s structure. A set of outdoor measurement results are given and analyzed.
