基于灰关联分析的目标识别方法研究

深入研究了灰关联分析方法在目标识别中的应用，提出了基于灰关联分析的目标识别方案，给出了对目标声信号进行灰关联分析的方法和步骤，并以此作为灰色目标识别的基础，在此基础上，利用舰船声场通过特性仿真数据建立了典型目标的模本数据和待识目标样本数据，进行了舰船目标声信号的灰关联分析，确定了目标识别与分类的判据，对两类舰船目标类型进行了识别，从而验证了灰关联分析方法应用于目标识别的可行性和有效性。

A New Approach to Target Recognition Based on Gray Correlation Analysis

The application of gray correlation analysis method in target recognition is deeply studied. The target recognition scheme based on gray correlation analysis is designed. The method and steps of gray correlation analysis of target noise are set up as the basis of gray target recognition. On the base of it, the model data of typical target and the sample data of recognized target are calculated with large quantity simulation data of target noise. The ship noises are analyzed by gray correlation method. The target recognition criterions are defined and the types of two ships are recognized. The feasibility and availability, which gray correlation analysis method is adopted in target recognition, are tested and verified.
