Abstract
Systems and method herein provide for laser detection and ranging (LADAR). In one embodiment, a LADAR system includes a transmitter operable to switch continuous wave (CW) laser light between the two or more polarizations based on a code, and to transmit the two or more polarizations of the CW laser light at a target. The LADAR system also includes a receiver operable to detect the two or more polarizations of the CW laser light reflected from the target. The LADAR system also includes a processor operable to determine a range of the target based on a time of flight of the switched polarizations of the CW laser light from the transmitter to the receiver according to the code.
