Measurement method of the object surface deflections using antennas theory




antenna array, antenna directivity pattern, reconstructed surface deflections, genetic algorithm


The method of remote measurement of object surface deflections using an artificially created system of secondary radiators located on this surface is considered. The physical basis of the method is a change of the pattern of radiators system due to their displacement under the loads influence. Radiators displacements which are included in the expression for the distorted antenna radiation pattern are determined by minimizing of the functional using a genetic algorithm. Reconstruction errors of radiators displacements are identified for different situations taking into account the ambiguity of the problem. The best conditions for the functioning of the method are recommended for the practical use.
