Patent ID: 8526671

Claim:
A sensor for detecting a firing of a munition towards said sensor from any line-of-sight location with a 360-degree circle surrounding said sensor; the sensor comprising: a cylindrical window, said cylindrical window having a 360-degree horizontal field of view to receive an electro-optical signal in a 360degree radius; refractive optics to capture and condense the received electro-optical signal, at least part of said refractive optics being disposed within an inner wall of a cylinder defined by said cylindrical window, said refractive optics including a reflector device to redirect the received electro-optical signal; and a series of refracting and focusing elements; a filter unit to remove all but a wavelength range generated by combustion of a chemical contained in a munition propellant from said condensed electro-optical signal; a relay device to transmit the filtered electro-optical signal to an image sensor; an image sensor to detect said relayed electro-optical signal and transmit corresponding detection data to subsequent alarm, display, targeting, or processing devices; and a reflector deforming device that allows the reflector to be made longer or shorter and wider or narrower, thereby adjusting a vertical field of view of said sensor.
