| 摘 要： | 在综合考虑背景辐射、光学系统近场辐射、探测器及其后续处理电路和焦平面非均匀性噪声影响的基础上，建立了拦截器导引头红外传感器的探测性能模型。根据文献给定的拦截器导引头参数对模型进行了验证，并利用所建立的模型分析了背景辐射对拦截器探测性能的影响。提出的方法和模型具有通用性，可用于分析背景辐射影响下各种拦截器红外导引头的探测能力。

| Abstract: | By considering the combined effects of background radiation, near-field radiation of optical systems, detector noise, noises due to electronic circuits, as well as the non-uniformity of an infrared focal plane array (FPA), a detection performance model for infrared (IR) sensors of interceptor seekers is developed. The model is validated using the reference published parameters of an interceptor seeker. The effect of observing backgrounds on system detection performance is analyzed. The proposed method and model can be used to analyze the detection performance of different interceptor’s IR seekers under background radiation. |
