Abstract： To reasearch on the infrared target perception by pyroelectric infrared (PIR) sensor in network domain measurement, a closed sensing network domain composed of eight-PIR-sensor array is proposed for the minimum sensing cell measurement in network domain and to realize the moving target perception and trajectory prediction. Moreover, the feasibility and accuracy of the proposed method are verified through experiments. The experimental results demonstrate that the maximum error between the real trajectory and the predicted trajectory of the minimum sensing cell measurement method is 0.64 m, which can achieve infrared target perception and moving trajectory prediction.
