ABSTRACT:
A method and apparatus detects and identifies targets using a laser and operating in accordance with Doppler radar techniques. A laser sensor comprises a laser transmitter and an optical superheterodyne receiver and detects characteristic surface vibrations of targets and derives, from the laser echo signals, after frequency conversion and demodulation, low frequency oscillations having the frequencies of the vibration spectrum, from which, through comparison with patterns of known targets, provides detection and identification of the target.
