Development of a 1310-nm, Coherent Laser Radar with RF Pulse Compression
NASA, ESA, and NASDA are planning to launch several satellites with LIDARs on board to measure ice sheet surface elevation, vegetation characteristics, and aerosol characteristics. LIDARs on these satellites will transmit short, high-peak power pulses to obtain adequate detection sensitivity and res...
