Abstract:

The report summarizes the work done during the period between April 1964 and June 1971 in developing and testing a laser radar technique to obtain backscattered signals from the atmosphere at altitudes up to 100 km. A vertically directed pulsed ruby laser signal with a 10 joule, 10 microsecond pulse provided the transmitted energy and an array of 30 inch diameter spherical mirrors provided a mirror area of 15 square meters to collect the backscattered energy. Photon counting techniques were utilized for high altitude returns and many returns are integrated to provide high sensitivity and to reduce the variance of the signals.
