远红外激光主动探测设备利用"猫眼"效应原理,能够快速、准确地发现红外热像仪,输出带有热像仪参数的信息.大气湍流是影响主动探测回波率的重要因素.在某沙漠地区的试验结果表明:日出、日落前后大气湍流的强度最小,对主动探测回波率的影响也最小.而中午前后、午夜前后湍流强度则相对较大,大气湍流对回波率的影响也较大.通过将试验结果和美国白沙试验基地(沙漠)一天内湍流变化数据进行对照,可以得出:上述现象是沙漠地区的普遍现象.总结出了大气湍流对激光主动探测影响的规律,为远红外激光主动探测设备能力评估提供了重要依据.

The system of the active far IR laser detection can rapidly find infrared thermal imager at high precision with the "cat eye" effect, and output the information of infrared thermal imager as well. The atmospheric turbulence was the important influence factor of the echo ratio of active detection. The test results in deserts showed that the intensity of atmospheric turbulence was weaker at sunrise or sunset, and was stronger at noon and midnight. Therefore, the influence on the echo ratio of active detection changed with the same trend as the intensity change of atmospheric turbulence. Comparing the experimental results with the experimental data of atmospheric turbulence in White Sands obtained in one day, conclusion is drawn that the above mentioned phenomena are general in desert area.The influence rules of the atmospheric turbulence on the active laser detection were summarized.It provides an important basis on the performance evaluation of the active far IR laser detection.
