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, the simulation test can predict whether the performance of the equipment meets the design requirements early in the equipment development, shorten the development cycle and reduce the development cost. The airborne test process of aerial photoimaging reconnaissance equipment is described and the framework of equipment simulation system is established. On the basis of this, the signal to noise ratio model of equipment in airborne test environment is established based on signal detection and matched filter theory. Method of predicting ground resolution of equipment. Through the example verification, the model is reliable and the prediction result is accurate.
