A multiple frequency laser technique for enhancing the detection of discrete targets amid a
clutter background while also increasing the range performance or power limits of the laser …

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 …

A pulsed laser radar apparatus utilizing a Q-switched laser unit to generate laser pulse
signals including a low intensity trailing tail. The trailing tail is utilized to provide a local …

ASSistant Examiner Brian Andrea (57) ABSTRACT A coherent laser radar System includes
a pulsed laser oscil lating a pulsed laser beam which is split into two parts by an optical …

Abstract AN IMPROVED LASER RADAR SYSTEM COMPRISES A VARIABLE PULSE
LASER TRANSMITTER A PORTION OF THE OUTPUT OF WHICH IS DELAYED …

In an eye-safe coherent laser radar, a laser diode optically pumps a solid state non-planar
ring laser to produce the coherent output laser radiation. The laser radiation is passed …

It is therefore the primary object of the present inven tion to provide a pulsed laser radar in
which the fre quency of the output laser beam is always at a fixed frequency difference from …

In a laser radar system, in which pulses from a laser are focused by a telescope onto a
target, the back-scattered radiation being deflected by polarizing beam splitter onto a …

The present invention is directed to a unique laser radar system realized by combining a
frequency agile source of coherent radiation with a staring detector system, ie, a detector …

57 ABSTRACT A laser beam is expanded by means of a beam expander device, the
expanded beam striking the surface of a mirror which has an aperture formed therein. A …
