摘要:
An arrangement for correcting deviations from the true bearing due to the effects of specular reflecting surfaces in target tracking radar installations having at least three primary feeds. At least two of the primary feeds are aligned such that a plane formed by the longitudinal axes of their radiation characteristics is disposed at least approximately perpendicular to the specular reflecting surface. At least one further primary feed is arranged such that the longitudinal axis of its radiation characteristic is located externally of such plane. A summation-difference network produces from the echo signals received by the primary feeds, apart from a summation signal, also two difference signals, and a cross-term signal formed in at least one measurement interval. From these signals there is produced an angle error signal which is divided into two components. In a signal processing stage there is obtained a correction signal in order to correct the angle error signal falsified by the specular reflection effects.
