摘　　要：为了实现距离维高达 0. 3m的高分辨率成像,逆合成孔径单脉冲雷达采用了宽带接收、宽带信号的产生与处理技术。综述了应用于ISAR中的X波段 1GHz宽带接收系统的关键技术问题和接收系统的设计与实现。讨论了去斜接收、指标分配、信号产生、通道设计等关键技术,并给出了研制方案和实测数据。In order to realize high resolution imaging with the accuracy of 0.3 m in the range dimension, the inverse synthetic aperture monopulse radar adopted wide band signal receiving, generating and processing technology. The key technologies of ISAR's X band receiver system with the 1 GHz bandwidth are described, including dechirp receiving, index distribution, signal generating, channel's designing. In addition the receiver system's design and realization are also described. And the development project and the experimental result are given.
