摘　　要：利用高频近似法分析了散射原理,得到了时域复杂形状导电体的散射场,并研究了导电体基于背投影算法的时城SMEP(Sine-Modulated Exponential Pulse)响应成像。经计算机模拟,实现得到缩比飞机模型清晰的像,表明该方法是雷达成像系统的一种有效手段。Analyzes the scattering mechanisms, this paper gives the scattered field of a complex shaped conducting object from high frequency approximation method, investigates time domain imaging of employing SMEP responses, and interprets the reconstructed image based on the back-projection algorithm utilized in image retrieval. Experiment results show that the described method can be a cost-effective approach in radar imaging systems.
