Evaluation and correction methods for antenna measurements

Abstract [en]

Test measurements of antennas are often made on some kind of range. These measurements has great demands of precision and improving the methods of evaluating the range must constantly be refined. The task has been to evaluate the range at Saab Ericsson Space by spherical probing. A number of methods has been studied and finally a method depending on a paper by Ronald C. Wittman was found the most suitable. Wittman describes how to calculate the incident field inside a measured sphere. Theese calculations proved to be very difficult and it resulted in the fact that a reasonable result of the measured field could not be obtained within the time frames of this project. The authors believe that the errors arise when the matrices and coordinate systems are beeing transformed between the many MATLAB-scripts. Further refining the scripts are therefore needed to be able to do an evaluation of the range with this method.
