Abstract

The experimental Infrared Ranging and Tracking System (IRATE) described herein has been developed for evaluating the capabilities of TEA-0O2 laser radars with heterodyne detection for the ranging and tracking of air targets. This system has been used in field measurements for investigating the return-signal fluctuations resulting from atmospheric turbulence and target induced speckle. Results are presented for measurements on single glint and diffuse reference targets with the system operating in both the heterodyne and direct modes of detection. The feasibility of angle tracking has been demonstrated but additional effort is required for determining system capabilities. The long-range performance of a TEA-CO2 laser radar with heterodyne detection was demonstrated by detecting returns with a high signal-to-noise ratio from mountains at 24.4 km.
