摘要
根据复杂目标在超宽带信号照射下的电磁散射特性 ,建立起超宽带雷达目标合理的冲击响应模型 ,并分别针对线性调频、冲击、二相编码无载波等三种典型超宽带雷达信号 ,确定了给定目标的回波特征 ,对回波相关处理的结果表明 ,其输出能反映出目标特征 ,有利于雷达目标的识别。
In this paper, based on the EM scattering properties illuminated by ultra-wideband (UWB) signals, the impulse response model is established. In allusion to the three kinds of UWB signal, such as LFM, impulse, carrier-free coded waveforms, the given target signature is studied. The correlation processing results show that the return reflects the target signature, and can identify the target.
