Aiming to the traditional acoustic detection array with measuring the target coordinate, the accuracy of measurement data is affected by the propagation velocity of the acoustic pressure. This paper proposes a new measurement method, which obtain the mathematical model of the target parameter information when the target passing through acoustic sensor array based on acoustic array structure establish. From the model the target parameter information is just associated with the respective probe element’s delay time of the acoustic pressure when the target passing through the acoustic detector, thereby it is effective to avoid the measurement accuracy influence from acoustic pressure velocity of the target parameter information. In order to obtaining the signal characteristics when the target passing through acoustic detector array, it would adopt time-frequency transform method to analyzed signals of the target through the acoustic array. By the simulation experiment it can improve the measurement precision of the target parameters information, and get frequency-domain characteristics of target information based on the measured analog signals of acoustic pressure. The result is benefit to enhance precision of target parameter information from acoustic array detection system, and it has certain guiding significance for the study of acoustic array structure.
