Abstract: Pyroelectric infrared sensor is highly precise in direction-finding, but not in distance measurement because of the influence of the complex environment. In the case of only considering the target direction, detecting angle and detecting line are defined, and a target localisation model based on detecting line sequence was developed. The model's solution is analysed in detail. When at least four detecting lines can be obtained, among which two existing parallel detecting lines are not parallel with at least two of the others, the target's moving trajectory could be determined uniquely. In the linear and curvilinear motion experiment, the maximum error is 0.35 m and 0.45 m, respectively. The findings demonstrated the effectiveness of the method.

Keywords: pyroelectric infrared sensors; dynamic sensing; detecting angle; detecting line; localisation models; target localisation; modelling; target trajectory; moving trajectory.
