DETAILED DATA ANALYSIS OF ECHO I, ECHO II AND MOON REFLECTED SIGNALS. VOLUME 4. THE LONG-TERM AUTOCORRELATION FUNCTION OF ECHO II REFLECTED SIGNALS,

Abstract

It is concluded that Echo II is apparently rotating in its orbit with a period between 90 and 95 seconds and that the ratio of extreme radii of curvature is 1.03, representing essentially a spherical reflector for the aspect angles involved in the measurement. (Author)
