Abstract
An embodiment of a directional ultrasonic gas leak detector includes an array of spaced MEMS microphones, each responsive to incident airborne ultrasonic energy from gas leak sources to generate a microphone signal. A beamforming processor is responsive to the microphone signals from the array to generate processor output signals indicative of estimated angles of arrival of ultrasonic energy incident on the array. The array may be disposed in an explosion proof housing structure for operation in hazardous location, or implemented as an intrinsically safe device. In another embodiment, a display is responsive to the processor output signals to generate an image representative of a surveilled scene with the estimated magnitudes of incident energy at beam directions overlaid onto the image.
