An infrared Doppler radar using a CO2 laser with FMCW coding
Abstract
The 'Finder' FM CW IR Doppler radar presented, which operates at 10.6 microns, has been developed to furnish a flexible tool for the investigation of CO2 laser systems performance in a variety of applications. Attention is given to the conditions and choices that would determine the character of the transmitted waveforms, and results are presented for range and velocity that have been compiled from spectra obtained from stationary and moving targets under various weather conditions. It is noted that the nonlinearity of the chirp waveform introduced by the modulator results in a broadening of the spectral output of the signal processing systems.
