Laser Radar Ranging and Atmospheric Lidar Techniques | 1997

Two-color SLR experiments at the GSFC 1.2-m telescope

Thomas W. Zagwodzki; Jan F. McGarry; John J. Degnan; Thomas Varghese

Satellite range measurements which include differential time of flight measurement between simultaneous doubled and tripled Nd:YAG laser pulses are being made at the NASA/Goddard Space Flight Centers 1.2m telescope tracking facility. A description of the streak camera-based range receiver is given along with the differential time of flight measurement. Typical streak camera return waveforms are displayed from satellite tracks which include: ADEOS/RIS, AJISAI, GFZ-1, STELLA, and TOPEX.
