Analysis and design of retrodirective arrays for multiple-interrogator environments

M.S. University of Hawaii at Manoa 2010.Includes bibliographical references.Retrodirective arrays are an attractive technology for mobile, wireless devices be-cause of their capability to autonomous steer a beam. This thesis focuses on the analysis and design of retrodirective-array technology for multiple-interrogator environments. A perfor-mance assessment of the phase-conjugating retrodirective array architecture in the presence of multiple interrogators is performed, showing that the phase-conjugating retrodirective array can retrordirect toward multiple interrogators. A retrodirective array architecture that uses interleaved retrodirective sub-arrays is presented. This interleaved retrodirective array is able to retrodirect its beam toward a single interrogator, while steering a null in a different direction, which can be used for interference rejection
