热释电红外敏感器是灵巧弹药进行目标自主探测与识别的主要探测器之一。本文从热释电红外敏感器的工作原理入手,结合弹药扫描平台参数散布和弹目交汇的各种情况,分析了热释电红外敏感器响应信号与子弹转速、弹目距离、目标宽度间的关系,为热释电红外敏感器设计时选择合理的热时间常数、电时间常数提供依据,也为灵巧弹药自主识别用目标特征的提取提供依据。

Pyroelectricinfrared sensor is one of the main autonomous target detection and recognition of the smart ammunition. This article analyses the relationships between pyroelectric infrared sensor response signal and the bullet speed distance from ammunition to target the target width and so on, from the working principle of pyroelectric infrared sensor, all with ammunition scanning platform parameters dispersion and all kinds of ammunition target intersection. The research provides the basis for choosing electro time constant the thermal time constant of the pyroelectric infrared sensor design, also for extracting target feature of the smart ammunition autonomuous recognition.
