Abstract: The triplet linear array is consisted of three piezoelectric transducers located in line. Passive directing and ranging with triplet linear array is a very useful method for target detecting. In this paper, we presented the principle of passive localization with triplet linear array and the formula for calculating target’s location. The theoretical analysis of various error sources that influenced the positioning accuracy when the triplet linear array had shape distortion was described. At last, the effect of shape distortion on passive localization was summarized by simulation experiments.


Keywords: Piezoelectric transducer, Triplet linear array, Passive localization, Shape distortion
