Claim Text:
1. A system comprising: a plurality of sensors configured to obtain far-field measurements of an electromagnetic field established by a radiating antenna, the far-field measurements providing a subsampling of a far-field antenna pattern corresponding to the electromagnetic field; at least one device configured to provide design information substantially corresponding to the radiating antenna, the design information including predetermined physical configuration data and predetermined electrical excitation data; a controller coupled to the plurality of sensors and the at least one device, the controller being configured to derive an initial data estimate of the radiating antenna pattern based on the design information and compare corresponding portions of the initial data estimate of the radiating antenna pattern to data corresponding to the subsampling of the far-field antenna pattern, the controller being further configured to iteratively obtain at least one intermediate data estimate of the radiating antenna pattern until a final estimate of the radiating antenna pattern is obtained, the at least one intermediate data estimate is identified as the final estimate when a comparison value, based on a difference between the data corresponding to the subsampling of the far-field antenna pattern and the at least one intermediate data estimate of the radiating antenna pattern, is less than a predetermined amount or when a predetermined number of iterations is reached, the controller being further configured to provide extrapolated operational data corresponding to the final data estimate, the extrapolated operational data including extrapolated physical configuration data and extrapolated electrical excitation data substantially corresponding to an operational state of the radiating antenna; and at least one output device coupled to the controller, the at least one output device being selected from a group of output devices including an antenna calibration unit, an antenna component replacement unit, a display device, or a remote unit accessible via an external network, the at least one output device being configured to perform an antenna related action based on a comparison of the design information and the extrapolated operational data.
