FM-CW laser radar at 10.6 microns

, 1974
The feasibility of a continuous -wave frequency-modulated radar with a CO- laser as a transmitting source was investigated. A developmental system was constructed and tested and the feasibility of an optical radar utilizing coherent detection at 10.6 microns was demonstrated.

A simplified, CW, random-noise radar system

, 1969
Experiments with a CW, random-noise, X-band, radar ranging system are presented, following the technique proposed and used by G. L. Poirier. The correlation signal-processing method differs from that of other noise radars in that no delay lines are required. The signal-processing technique also decorrelates clutter and other interference, including the
