Paper Abstract

This paper describes the breadboard of a coherent imaging infrared radar, which is based upon the use of a continuous wave CO2 laser and can operate in three different modes invol-ving frequency modulation/demodulation processing techniques, i.e. Linear Frequency Modulation (or chirp) pulse compression, FMCW (triangular Frequency modulation) and CW (or offset homodyne). In each mode of operation, this laser radar delivers two dimensional images of a scene, coded in range and/or Doppler velocity, and/or reflectance. After recalling the basic principles of these techniques, one describes their experimental implementation and compares their performance.
