摘　　要：仿真试验通过构建数字化的试验环境,在装备研制初期就可以预测装备的性能是否满足设计要求,缩短了研制周期,降低了研制成本。阐述了航空光电成像侦察装备的机载试验过程,构建了装备仿真系统框架,在此基础上,基于信号检测和匹配滤波器理论建立了机载试验环境下装备的信噪比模型,给出了预测装备地面分辨率的方法。通过实例验证,该模型可靠,预测结果准确。By building a digital test environment,simulation experiment can predict that whether the performance of equipment meet the design demands during the initial stage of development,it has such merit as shorting the develop period and saving the military spending.The process of airborne experiment is described,the simulation system framework is designed,taking the simulation system framework as foundation,based on the signal detection theory and matched filter＇s thought,the signal-to-noise ratio model which under the airborne experimental environment is established,the method for predicting the ground resolve distance of equipment is realized.A case illustrates that the simulation model is reliable and the prediction results is accurate.
