摘要

通过测量热释电信号峰—峰值的时间差

可以计算目标到探测器之间的距离。当目标人员垂直穿过热释电传感器探测视场时

能够很好地测得距离的大小。而对于目标人员斜切进入探测视场时

现有的方法就出现了较大的误差。因此

在实验的基础上

对原有测距算法进行改进和修正

实现了人员目标30 m范围内以60°角斜切进入探测视场的有效测量

拓宽了时间差法测距的适用范围

具有较好的应用价值与市场前景。

Abstract

By measuring time difference peak to peak value of pyroelectric signal

distance from target to detector can be calculated. When the target personnel vertically passing through pyroelectric sensor detection field

distance value can be well measured. As for the target personnel is beveling into the detection field

the existing distancemeasuring methods appear larger error. Therefore

on the basis of experiment

improve and revise the existing algorithm

achieve effective measurement when target is beveling into detection field with 60° of view in range of 30 m

broadens application scope of time difference method for distance-measuring

and has good application value and market prospects.
