Real-Time Imaging with a Pulsed Coherent CO, Laser Radar

Abstract

Textron has designed and built under the HI-CLASS (FLD) program a high- powered CO2 laser radar for long range targeting and remote sensing. This is a coherent, multi-wavelength system with a two dimensional, wide-band image processing capability. The digital processor produces several output products from the transmitter return signals including range, velocity, angle, and two- dimensional range-Doppler images of hard-body targets. In addition, the processor sorts and reports on data acquired from gaseous targets by wavelength and integrated path absorption. The digital output products are produced in real time and stored off-line for post-mission analysis and further target enhancements. The digital processing algorithms are designed to extract certain features from operation on each of the waveforms. The waveforms are a pulse-tone and a pulse-burst designed for target acquisition and track, and two dimensional imaging (range-Doppler) respectively.
