ABSTRACT:
The time separation of laser pulses comprised of a relatively fixed reference pulse and a time varying doublet pulse in a doublet pulse laser radar is linearly modulated for eliminating velocity ambiguity upon reception and detection. A range-Doppler map can be directly generated which not only reveals target range and velocity, but also can be processed to indicate target motion, such as rotation.
