Abstract
A laser radar system is disclosed. The laser radar system includes a transmitting means that transmits a signal. The transmitted signal is formed by an optical signal that is amplitude modulated with a source signal thereby forming a transmitted signal having light packets at a repetition rate of the source signal. A receiving means that receives the transmitted signal after it is reflected from an object. A Doppler processor determines the Doppler frequency shift of the source signal from signals derived from the reflected signal.
