Abstract: A PORTABLE THREAT DETECTION APPARATUS (20) AND METHOD IS DISCLOSED WHICH MAY COMPRISE A PLURALITY OF ACOUSTIC EMISSION SENSORS (40) ARRANGED IN A CLUSTER (22), FORMING A POLYGON DEFINING AT LEAST TWO AXES OF ALIGNMENT BETWEEN RESPECTIVE PAIRS OF ACOUSTIC EMISSION SENSORS (40); A COMPUTING DEVICE (60) IN COOPERATION WITH A NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM COMPRISING COMPUTER READABLE INSTRUCTIONS FOR PERFORMING: RECEIVING A FIRST SIGNAL PRODUCED BY A FIRST ACOUSTIC EMISSION SENSOR (40) WITHIN A RESPECTIVE PAIR OF ACOUSTIC EMISSION SENSORS (40), IN RESPONSE TO THE FIRST ACOUSTIC EMISSION SENSOR (40) DETECTING AN ACOUSTIC EMISSION FROM A SOURCE, AND RECEIVING A SECOND SIGNAL PRODUCED BY A SECOND ACOUSTIC EMISSION SENSOR (40) WITHIN THE RESPECTIVE PAIR OF ACOUSTIC EMISSION SENSORS (40), IN RESPONSE TO THE SECOND ACOUSTIC EMISSION SENSOR (40) DETECTING THE ACOUSTIC EMISSION; DETERMINING A CROSS-CORRELATION FACTOR BETWEEN THE FIRST SIGNAL AND THE SECOND SIGNAL; AND, DETERMINING A BEARING TO THE SOURCE BASED ON THE CROSS CORRELATION FACTOR.
