METHOD FOR DETERMINING POSITION OF A RIFLEMAN IN AN AREA Russian patent published in 2006 - IPC G01S5/18 G01S3/80 

FIELD: measuring equipment engineering, in particular, technology for detecting position of an object using sound waves, in particular, for determining position of rifleman in an area.

SUBSTANCE: in accordance to method, recording of sound signals is enabled in case of registration of impact waves from by-flying ultrasound bullet and barrel wave from expanding gases from barrel edge by sensitive elements, processing of these signals by means of processor, on basis of results of which position of sound source is determined. Method contains following innovations: sensitive elements are preliminarily fastened immovably relatively to optical axis of video recording device, synchronously with recording of sound signal by not less than 3 sensitive elements, recording of video image of possible position of sound source is performed by means of at least one video recording device, mounted with possible change of filming direction and position in space, during following processing of signals moment of arrival of barrel wave and frame from recorded video row, closest to aforementioned moment, are combined, and mark of rifleman position is placed on that frame. Recording of video image is performed in optical or infrasound or other range.

EFFECT: improved safety, possible finding of direction towards position of an enemy, possible determining of distance to enemy by creating a method making it possible not only to determine direction towards sound source, but also to detect ("see") it.
