摘要：
The methods which makes possible to calculate errors in taking bearing to an aerodynamic object of a complex shape are presented. The direction finder is located in a near zone of a scatterer. It is shown that the errors have been mainly caused by distortions in the amplitude-phase distribution of a field in the receiving antenna aperture. As the distance to an object decreases, angular deviations increase and may become considerable. The results of calculations of amplitude-phase distributions of the field in the aperture and the corresponding bearing errors for an airplane with a maximum cross size of 20 meters are represented. © 2004 Begell House, Inc.
