摘要
基于实验室通用设备矢量网络分析仪和滑轨的合成孔径成像系统可以获取低成本实测数据,验证成像原理和算法;可以通过设置不同系统参数评估系统性能,为实际系统的搭建提供有效的论证。介绍了如何采用C#编程联合控制矢量网络分析仪和滑轨,以及对目标"一步一停"测量的方法。最后通过实测数据S21参数获得目标延时特性,分别进行距离向和方位向处理对目标进行二维成像,通过对目标成像结果和实际空间位置的比对,验证了该方案的可行性和有效性。
The system of synthetic aperture radar imaging based on vector network analyzer and sliding rail,which are general equipments in laboratory,can acquire low-cost data to validate the theory and algorithm of imaging and provide effective validation of real system construction.The combined control of vector network analyzer and sliding rail by C# codes and the＂Stop-Go＂method of measurement for objects are demonstrated.At last,through the time-delay characteristics of the measured data of S21 parameter,the objects are two-dimensionally imaged by range and azimuth processing.In compare with the real spatial positions of the objects,the system is proved to be valid and effective.
