FIVE- ELEMENT PLANAR CROSS ARRAY PASSIVE LOCATION BASED ON MUTUAL INFORMATION

Passive acoustic source location and tracking can be implemented by microphone array, which have a broad application on target detection and fault diagnosis etc. Five-element planar cross array is an effective structure for acoustic source location, but bad location results are often obtained by conventional relative acoustic source location methods in complicated environments. This paper proposed a novel passive acoustic source location method based on mutual information and thoroughly analyzed this new location algorithm. Experiments show that a more stable and accurate location results may be obtained by this new location method. The implementation of this location method is relatively simple and effective, which can satisfy the demand of engineering application
