天线时域近场测试平面的结果显示系统

Visualization System to Exhibit Results of Antenna Near-Field Scanning in Time Domain

为了解决时域近场平面测试中结果显示系统配套的问题,通过修改数据处理过程中的计算方式,输出不同的显示数据格式,提出了一种应用于倾斜主瓣的主平面剖分方法,在频域范围内对倾斜主瓣的主平面剖分进行了研究,给出了一种实用的新型倾斜主瓣主平面剖分与显示方法,得到一套较为完善的时域结果显示系统.研究结果表明,该系统实现了时域动态显示功能,达到了时域近场平面测试系统时域分析的要求,基本满足时域近场平面天线测试需要.

In order to solve the problem of matching the result visualization system with antenna near-field scanning in time domain,the output data that exhibits the features of time domain were obtained by adjusting computing mode in data processing.In addition,a new method was proposed to obtain the inclined main lobes and display it in time domain.As a whole,a result visualization system suits for antenna near-field scanning in time domain was achieved.The realized visualization system meets the function of dynamic display and the request to exhibit the features of time domain analysis.The requirements of antenna near-field scanning in the time domain are satisfied basically.
