1. A method of detecting camouflaged or concealed objects in an interrogation region having foliage, comprising: receiving at a two-dimensional (2-D) photodetector array at least a portion of reflected light from said interrogation region including at least an ultraviolet (UV) comprising band and simultaneously capturing at least one reference band comprising near infrared (NIR) light while simultaneously filtering out green light, wherein said 2-D photodetector array comprises a plurality of photodetector pixels to provide sensitivity to at least said UV comprising band to capture a higher level of ultraviolet reflections from the camouflaged or concealed objects relative to ultraviolet reflections from the foliage; generating with said photodetector array at least a first detection signal from at least said UV comprising band; forming with a processor processed image data from data from at least said first detection signal; and identifying camouflaged or concealed objects distinguishable in said processed image data from the foliage within said interrogation region at least in part in response to the higher level of ultraviolet reflections captured by said photodetector array in said ultraviolet comprising band.
