In one embodiment, detecting a target includes directing a laser beam towards an area and detecting the laser beam reflected from the area. Whether the received laser beam comprises an optically augmented reflection indicating retro-reflection from a target is determined. The target indicates presence of an explosive device. The target is detected if the received laser beam comprises the optically augmented reflection.

What is claimed is: 1. A method for detecting a target, comprising:directing a laser beam towards an area;detecting, by a detector, the laser beam reflected from the area;determining, by a control system, whether the received laser beam comprises an optically augmented reflection indicating retro-reflection optically augmented by a target, the target indicating presence of an explosive device, the determining comprising:receiving an orientation angle of the detector with respect to the ground;generating an image of the detected laser beam according to the received orientation angle of the detector with respect to the ground;generating a histogram from at least the image representing a plurality of grayscale values of the area, the histogram comprising a frequency count for each grayscale value; anddetermining that a particular frequency count of the histogram is greater than a threshold;detecting the target if the received laser beam comprises the optically augmented reflection; andestimating a location of the target according to an intensity and an angle of the detected laser beam, the location comprising Global Positioning Satellite (GPS) coordinates of the target.
