multi static radar based on meta - material and the method of calibration for the detection of obstacles and the distances of the objects electromagnetic reflection

摘要

the present invention relates to a multi static radar based on meta materials and a method of calibration for the detection of objects and distances, which are regarded as objects.o electromagnetic reflectors.the radar is characterized in that it includes a device (300) is placed between each pair of electromagnetic decoupling antenna (110) receiving antenna adjacent (120, 130).the device has a pyramidal shape formed by a base (301) to remove the coupling, and at least two planar surfaces (302)303) to eliminate the coupling of an angle is formed between the front and the other at the base of the pyramid structure (300) of the electromagnetic absorber.the angle is less than or equal to the angle made between the axis (115, 135) of the main lobe (111, 131) and the axis (116, 136) of the side lobe (112)(132) of the radiation pattern of the antenna adjacent to the planar face of the pyramid structure (300).the invention relates to a method for the calibration of multi static radar obstacle detection and distance.
