红外探测设备抗烟幕干扰试验及评估方法

红外探测设备抗烟幕干扰能力是其抗干扰能力的重要部分。常规方法对场地和实施要求很高,试验次数安排有限。文章对该试验设计的关键问题开展分析和研究,根据红外探测设备作用距离与目标能量的关系,采用"等效试验"构建外场静态试验干扰环境,并合理选择试验因素采用均匀设计方法进行试验设计,确定抗干扰试验方案和评估方法。该方案可指导试验获得科学合理有效的数据,从而实现烟幕干扰环境下红外探测设备的抗干扰能力的准确评估。

Test Design and Evaluation Method of Infrared Detector Smoke Interference

Anti-jamming of smoke screen capability of infrared detector is an important part of anti-jamming capability. The requirements of conventional methods for the site and the implementation is high, and test times are limited. To effec? tive test,the key-problem was analyzed and studied. Firstly,according to the relationship between the distance and the tar? get energy of infrared detector, the interference environment of external field static test was constructed by equivalent test method. Then an uniform design method was used to test design. Finally,test execution plan and evaluation method is de? termined. The plan could guide the test to obtain the effective data,and the accurate evaluation of Anti-jamming of smoke screen capability of infrared detector was finished.
