| 摘 要： | 近场散射数据的远场变换研究是具有发展前景的由近场测量目标,获取目标远场雷达截面的方法之一。根据近场获得的散射数据,外推获取远场的目标散射特性。主要是利用平面波谱展开,推导了近远场转换公式;以导体圆柱、平板等简单物体作为散射体仿真了近场散射数据的远场变换,证明了方法的可行性和正确性。

| Abstract: | Near-field to far-field transformation ranks among one of the most promising methods for getting far-field radar-cross-section(RCS) from measurements of targets from the near-field scattering fields.These are discussed.The near-field to far-field transform formula is deduce to obtain base on synthetic plane waves(SPW).A right circular cylinder and plane target demonstrate its validity. |
