摘　　要：为满足多种型号雷达系统测试的要求,场景系统必须能产生多体制、高质量的雷达信号。提出一种通用雷达信号场景系统方案,以AWG7082C任意波形发生器、E8267D矢量信号源及N9030A矢量信号分析仪组成的具有校准功能的宽带信号调制系统,使用安捷伦Pulse Building软件编辑生成一系列常见的雷达信号。实验证明,该系统可生成多种体制高质量的雷达信号,特别是系统经校准后大幅抑制了镜频的影响,满足大多数雷达系统测试需要。To meet the needs of testing the majority of radar system, scene system must generate all kinds of high quality radar signal. A universal scene system for generating radar signal is proposed. There is a Broadband signal modulation system that has function of calibration, this system consist of AWG 7082C Arbitrary Waveform Generators, E8267D Vector signal generator and N9030A Signal Analyzer. It can compile a series of common radar signal by Pulse Building software. Test resuhs show that the system can create all kinds of radar signal to test most of radar system excellently, especially the calibrated system can restrain image frequency perfectly.
