摘　　要：本文在一定的基本假设条件下 ,利用湍流统计理论 ,研究了气体传感器的激励———地面作战平台尾气排放物的扩散模式 ,得到了多种战场环境下尾气排放物浓度的表达式。初步研究了气体传感器目标探测系统 ,进行了传感器的选型及静态标定研究 ,利用回归分析的方法 ,研究了其传输特性。对目标探测技术进行了研究 ,提出了初步探测方案。Dispersion models of vehicle exhaust, taken as the gas sensor stimulus, are studied with the theory of onflow. Expressions of exhaust denseness are put forward under many battlefield conditions. Through investigation systems of target detection, the paper selects and demarcates the type of gas sensor appropriate for use. Input output of the gas sensor is studied with regression analysis. The technique of target detection is studied and the basic scheme of detection is given. Target detection probability is obtained through computer random simulation under limited simulation conditions.
