雷达目标全极化一维距离像的瞬时测量方法

雷达目标宽带全极化测量在雷达成像、目标识别等领域有着重要应用,为此,基于正交频率分集思想,设计了一种用于宽带全极化瞬时测量的矢量信号波形;给出发射信号模型和回波信号模型,利用该波形的单个脉冲回波,可以获取测量带宽内多频点全极化数据,再经逆离散傅立叶变换后可以得到目标的全极化一维距离像;最后,用仿真数据和实测数据进行仿真实验,验证了该方法的有效性.

Instantaneous Measuring Method of Radar Target Full-polarization Range Profiles

Wideband full-polarization measurement for radar target is of important application in the research fields of radar imaging and target recognition.Based on orthogonal frequency division and full-polarization instantaneous measuring method,a new waveform vector was designed to get full-polarization information simultaneously under wideband condition.Firstly,the models of emitting and receiving signals were given,and full-polarization datum in frequency could be gathered,and then target full-polarization rang...
