高分辨雷达目标回波信号模拟与分析

对高频区复杂目标的散射特性进行分析，建立了基于多散射中心的高分辨雷达目标回波模型，在此基础上对线性调频信号进行模拟，生成目标的回波数据，同时给出了脉冲体制雷达数据采集和存储方法的模型。为验证回波模型的有效性，对仿真的回波数据分别进行脉冲压缩和多普勒处理，处理结果正确反映出目标特征，表明模型可行有效。研究结果可为目标特征提取、目标识别提供技术基础。

Simulation and analysis of target echo signal of high-resolution radar

The paper analyzes the scattering properties of complex targets of high-frequency region and establishes the high-resolution radar echo model based on multi-scattering centers. On this basis,the target echo data is generated after simulation of chirp signal and the model of data collection and storage of pulse-radar is also given. The simulated echo data is processed by pulse-compression and Doppler processing to verify the validity of echo models. The result reflects the characteristics of targets and so the model is feasible and effective. The conclusion provides a technical basis for target feature extraction and object recognition.
