摘要
分析和推导了红外成像导引头用于探测点源目标时探测距离的评价参数,并比较不同测试参数的优缺点。从分析点源目标的特性出发,分别推导出NEFD和NETD与探测距离的关系模型。最后,给出适合测试和评价红外成像导引头的参数。
The evaluation parameters of operation range of IR imaging seeker for spot target detection are analyzed and deduced, and their merits and demerits are compared. Based on the analysis for characteristics of point source, the models which the operation range for spot target relates with NEFD and NETD respectively are derived. Finally, the parameters suitable for testing and evaluating IR imaging seeker are given.
