A device for the three-dimensional acoustic detection and imaging via hexidrant isolation and delay mixing is comprised of one or more acoustic sensors capable of collecting one or more sets of acoustic data; and a computer processor configured to perform operations including at least: obtaining one or more sets of acoustic data from the one or more acoustic sensors; applying one or more time delays to the one or more sets of acoustic data from the one or more acoustic sensors to create one or more sets of delay data; combining the one or more sets of delay data from the one or more acoustic sensors into one or more sets of output data; and mapping the location of a source of the acoustic data based on the one or more time delays applied.

A method and a device for high frequency acoustic spectrum imaging for an object over a field of view. A camera captures an image of the object. A raster with grids is created as an overlay on the captured image. A directional microphone detects high frequency acoustic waves emanating from the object. An acoustic data signal corresponding to the high frequency acoustic waves is generated by a microphone data processing unit. The coordinates of the focal point of the directional microphone on the grid of the raster is recorded and sent as a real-time feedback position signal to a processor for each measurement of the acoustic signal data. The processor plots a visual representation of the acoustic signal data mapping it to the corresponding coordinates on the raster and creates a high frequency acoustic spectrum image for the object by superimposing the raster on the captured image.

Systems and methods are presented for detecting a direction of an incoming projectile and determining a source location of the projectile. One or more resonant sensors (comprising a plate, piezo electric sensor, etc.) can be arranged, where shockwaves from the projectile (e.g., shockwaves from a bullet travelling at supersonic speeds) are incident upon the plate and cause the plate to resonate. The resonance causes an electrical signal to be generated by the piezo electric sensor (e.g., a piezo electric film sensor), the greater the degree of resonance in the plate, the higher the magnitude of signal generated by the piezo electric sensor. By comparing the magnitude of the piezo electric signals across the array of resonant sensors it is possible to determine a trajectory of the projectile and hence a location of the source of the projectile. Acoustic waves can also be generated by muzzle waves.
