攻击机在对地面目标进行攻击前必须首先发现目标。目标发现概率受多方面因素的影响,包括目标的面积大小、分布、对比度等。在充分考虑目标发现概率各影响因素的基础上,建立了其空间几何模型;采用解析法建立了攻击机目标搜索模型;分析了对比度和能见距离对发现概率的影响。仿真结果显示,该模型正确反映了各影响因素与目标发现概率的关系,是一个有效的模型。

The attackers must discover the targets on the ground first before attacking them.The target detection probability is subject to the influences of many factors, including the area, distribution and contrast of the targets and so on.With full consideration of various factors that have effect on the discovering probability, the geometric model was established.Analytic method was used to build up a target searching model for the attacker, and the effect of contrast and visible distance on detection probability was analyzed.Simulation result showed that the model can exactly reflect the relation between the detection probability and the impact factors, which is a feasible model.
