Radar Target Angular Scintillation in Tracking and Guidance Systems Based on Echo Signal Phase front Distortion

摘要

The slope of the echo signal phase front from a finite-size complex target is identical to the angular error caused in tracking radars by target angular scintillation or target angle noise. Thus, the target angle noise is contained in the echo signal as a distortion of the phase front. This new concept aids in visualizing the source of target angle noise and in assessing, in general, the effects of target angular scintillation or target angle noise on any target locating device. As an example, identical errors in target location also occur in a search radar.
