利用频率步进脉冲技术提取一种坦克简化模型的距离回波波形．然后针对该模型就识别特征的提取、模式识别库的建立和几种背景条件下的识别概率等问题进行了探讨．通过实验获得了几种简单目标模型的高距离回波波形，说明了高距离分辨技术在目标识别领域的可行性． Using Frequency Step Pulse Technique to Extract the Distance Echo Waveform of a Tank Simplified Model. Then, this dissertation discusses the extraction of recognition features, the establishment of pattern recognition library and the recognition probability under several background conditions. The high-range echo waveforms of several simple target models are obtained through experiments, and the feasibility of high-range resolution in the field of target recognition is demonstrated.
