System for emitting electromagnetic beams, comprising a network of antennae
First Claim
1. A system for emitting electromagnetic beams, including a first network of elements for emitting far field electromagnetic beams, the signals stemming from and/or arriving at each of the elements being weighted by excitation coefficients digitally determined by computing means,comprising:
- a second distinct network of sensors which is distinct from the first network of elements and which is laid out in proximity to the first network of elements in order to measure the existing near field radiated by the elements,means for computing the far field radiated by the first network from the near field actually measured by the sensors,means for computing corrections of the excitation coefficients of the elements from the difference which exists between the far field computed from the measurement of the near field and a pre-determined set far field,the elements of the first network being attached to a first support, each sensor being attached to a second support distinct from the first support, the first support and the second support being attached to a common base with a space between the first support and each second support, the first support comprising a common plate supporting the elements of the first network, the plate including holes for the crossing of the second support with said space present between the edge of the hole and the second support, said space allowing deformation of the first support.

Abstract
This invention relates to a system for emitting electromagnetic beams, comprising a network of elements for the far-field emission of electromagnetic beams, the signals coming from and/or arriving towards each element weighted by excitation coefficients digitally determined by calculation means. According to the invention, the system comprises: a second separate network of sensors arranged close to the network of radiating elements in order to measure the near field radiated by the elements, means for calculating the far field radiated by the network from the near field actually measured by the sensors, and means for calculating the correction of the excitation coefficients of the elements from the difference between the far field calculated from the measurement of the near field and a pre-determined nominal far field.
