基于AHP和ADC的机载预警雷达对海探测效能评估

摘要

机载预警雷达对海探测效能跟雷达状态、技术指标和工作环境都有关系,为了实现预警雷达对海探测性能的定量评估引入了ADC和AHP模型.首先,建立了适用于机载预警雷达性能评估的ADC模型,给出了可用性因子、可靠性因子和能力因子的计算方法.然后,通过AHP给出了能力因子各级指标权重系数的计算方法,最后通过某典型机载预警雷达设备对所建模型进行了仿真验证.仿真结果表明,该模型能够定量评估机载预警雷达对海探测性能,准确体现各因素对雷达效能的影响.%As sea targets'detection and measuring capability varying with radar state , technical performance and working environment , ADC and AHP model were introduced in order to evaluate radar 's detection and measuring capability to sea quantitatively.To begin with, ADC model available to AEW radar 's capability evaluation was set up , as well as index of A-vailability, Dependability and Competence were provided .Afterward, hierarch of capability factors 'weight computing method was given based on AHP .Finally, the built model was validated by certain typical AEW radar 's emulation.Emulating result showed that the built modal could evaluate AEW radar 's detection and measuring capability to sea quantitatively , and factors' influence to capability was exhibited quantitatively .
