Therefore, a detection method with low power consumption is crucial for persistent surveillance to ensure longevity of the sensor networks. A simple and effective two-stage algorithm composed of energy detector (ED) and delay detector (DD) with all its operations in time-domain using small-aperture microphone array (SAMA) is proposed. The algorithm analyzes the quite different velocities between wind noise and sound waves to improve the detection capability of ED in the surveillance area. Experiments in four different fields with three types of vehicles show that the algorithm is robust to wind noise and the probability of detection and false alarm are 96.67% and 2.857%, respectively.<\/jats:p>","DOI":"10.3390\/s17030514","type":"journal-article","created":{"date-parts":[[2017,3,9]],"date-time":"2017-03-09T06:56:43Z","timestamp":1489042603000},"page":"514","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Design of an Acoustic Target Intrusion Detection System Based on Small-Aperture Microphone Array"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9479-0589","authenticated-orcid":false,"given":"Xingshui","family":"Zu","sequence":"first","affiliation":[{"name":"Science and Technology on Microsystem Laboratory, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 201800, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7468-5634","authenticated-orcid":false,"given":"Feng","family":"Guo","sequence":"additional","affiliation":[{"name":"Science and Technology on Microsystem Laboratory, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 201800, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingchang","family":"Huang","sequence":"additional","affiliation":[{"name":"IBM-Research China Lab, Shanghai 201203, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Science and Technology on Microsystem Laboratory, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 201800, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huawei","family":"Liu","sequence":"additional","affiliation":[{"name":"Science and Technology on Microsystem Laboratory, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 201800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7602-7136","authenticated-orcid":false,"given":"Baoqing","family":"Li","sequence":"additional","affiliation":[{"name":"Science and Technology on Microsystem Laboratory, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 201800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaobing","family":"Yuan","sequence":"additional","affiliation":[{"name":"Science and Technology on Microsystem Laboratory, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, Shanghai 201800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1564","DOI":"10.1109\/TPDS.2011.38","article-title":"Performance Analysis of Real-Time Detection in Fusion-Based Sensor Networks","volume":"22","author":"Tan","year":"2011","journal-title":"IEEE Trans.
