METHOD AND A DEVICE FOR EXTENDING THE ILLUMINATION OF A TEST OBJECT

The present disclosure provides a method and a corresponding device for extending the illumination of an object under investigation. The object under investigation is illuminated with an electromagnetic microwave signal which is transmitted from a transmission antenna. The microwave signal reflected from the object under investigation is received by at least one reception antenna. An image of the object under investigation is reconstructed through synthetic focusing of the reflected microwave signal. At least one reflector element is arranged orientated towards the object under investigation and the microwave signals reflected from the reflector element and from the object under investigation are received in a reception antenna and used for the reconstruction of the image of the object under investigation in addition to the microwave rays from a transmission antenna which strike the object under investigation without reflection on the reflector element and are received by the reception antenna without reflection on the reflector element.
