SOME CHARACTERISTICS OF RADAR ANGEL ECHOES
Abstract
Time lapse motion picture data was taken of AN/TPQ-11 A-scope radar response to invisible targets commonly referred to in the literature as angels. The information obtained permitted an evaluation of the peak power returned, the cross section of the radar target, the time during which the target intercepted the radar beam, and the apparent velocity of the target. The information recorded over a two-day period indicated that the echo characteristics are capable of being segregated and are reasonably consistent within each of three distinct periods. The nature of the information available from these data reveal some of the detailed manifestations of angel activity and suggest the possibility of learning more about this phenomenon so that its cause and origin may eventually be more clearly understood and predicted.
