Abstract
A method and apparatus are provided for detecting objects of interest using sounds. Sounds are monitored for using a sensor array. A number of beams are formed. Each beam in the number of beams is formed for a selected direction in which the selected direction for each beam is relative to a line of sight for the sensor array. A presence of a number of objects of interest is identified using the number of beams and the sounds detected by the sensor array.
Claims22
A method for detecting objects of interest using sounds, the method comprising:
- monitoring for the sounds using a sensor array of a plurality of microphones arranged in a uniform hexagonal array pattern;
