摘要：

Microwave systems for object detection and imaging usually illuminate a given scene and measure the reflected signals. One of the most important tasks is a rapid and efficient detection of the angular positions of the scatterers present in the scene. This task can be accomplished by designing a smart antenna composed of multiple receiving elements, which is able to estimate the angles of incidence of the incoming electromagnetic waves. In this paper, a new efficient method based on a support vector regression is proposed for the detection of arriving electromagnetic waves scattered by objects located both in the far-field and near-field regions of the smart antenna. The effectiveness of the proposed approach is evaluated by means of several numerical simulations.
