초록

It has been found that target optics produce non-specular, augmented optical returns when interrogated by a laser pulse. This non-specular radiation is detected by an active laser search system employing a direct-reading, thresholded focal plane detector that is able to detect non-cooperating targets with optics that employ a detector or optical element at the focal plane of their receiving optics. The pulses returned from such target optics have a width commensurate with the original transmitted pulse width, whereas passive background noise and the spre...

청구항

What is claimed is: 1. A method for identifying a target employing optics, comprising the steps of: illuminating a target having optics with an optical axis with a pulsed laser beam; and, detecting off-axis non-specular reflected returns from the optics of said target having pulse widths matching that of the pulse width of the pulses in the laser beam. 2. The method of claim 1, wherein said target illuminating step includes sweeping the beam from said laser over a predetermined area on the ground. 3. The method of claim 2, wherein the number of swe...
