摘　　要：在雷达试验评估过程中,被试雷达存在着多种技术状态,分析研究各类技术状态在特定条件的适应性是雷达试验评估过程中的一项重要工作。针对通常采用单因素调整法分析适应性存在的诸如因素与性能之间关系难以显示描述、精度不高、对技术状态动态变化难以表示等不足,引入"相对效率"的思想,给出了一种基于数据包络分析(Data Envelop-ment Analysis,DEA)的Malmquist指数法的因素作用测算方法,研究了雷达试验评估过程中动态变化的技术状态对特定条件的适应性。首先,阐述了DEA的Malmquist指数方法的基本理论;然后,根据雷达试验评估的实际背景和特点详细,结合基于DEA的Malmquist指数方法流程,给出了雷达试验评估中因素测算方法的决策单元(Decision Making Units,DMU)选取、输入-输出指标确定、DEA模型选择、距离函数模型选择的原则,讨论了方法的计算步骤和技术细节;最后,通过实例分析验证了方法的合理性和正确性,给出的结论对实际工作有一定的指导意义。In the process of guidance radar tests evaluation,there are many technical state of radar.It is an important work to analyze the adaptability of various types of technical state under the specific conditions in guidance radar tests evaluation process.Usually, it uses single factor adjusted method to analyze adaptability.But it＇s hard to describe the relationship between factor and performance and dynamic change of the technical state.Aimed to shortcomings of this method,it introduces an idea of＂relative efficiency＂,and the factor effect calculation method based on DEA and Malmquist index model is proposed.It studies the adaptability of dynamic change nature of technical state to specific conditions in the radar test evaluation process.First,the DEA Malmquist index theory is introduced. Then,According to the radar test evaluation actual characteristics and combining the flow of the Malmquist index method based on DEA,the principle of how to select the DMU,the input-output index,the DEA model and the distance function model is derived,and the calculation steps and technical details are discussed;At last,Simulation example analysis validate the rationality and correctness of this method,the conclusions have definite significance to practical work.
