Abstract

Abstract

Angular glints are the main error sources for radar angular measurement in the terminal guidance, which may result larger tracking error or even lead to losses of the tracking if mishandled. Although the angle glint can be suppressed to some extent through Higher Range Resolution Profile (HRRP) processing, the tracking errors due to multiple scattering centers can not be thoroughly eliminated. It is found in this paper that the tracking errors are closely related with the attributes of scattering centers. The influence on angular measurements induced by scattering centers with various attributes is investigated theoretically and numerically in this paper. For high reliability of numerical results, the scattering responses of extended targets are simulated by the scattered fields computed by the full-wave numerical method in this paper. The reached conclusion of this paper can provide a theoretical reference for the techniques in order to improve the tracing accuracy of extended targets with multiple scattering centers.
