Abstract

In this paper, an optical system is described that is an optical head of a coherent imaging CO₂ laser radar. Discrimination and field of regard limit decided by the optical head itself are discussed. In the experimental laser radar only one continuous wave, single mode CO₂ laser is used, and the signals from buildings of 7 km away are obtained with acceptable SNR while the laser output is about 5 w. Furthermore, the comparison between two optical systems based on individually linear frequency modulation (or chirp) pulse compression and frequency modulated continuous wave technique is also introduced in this paper.
