A retrodirective array designed to respond to nonuniform wavefronts is presented. The design overcomes the limitations of existing phase-detection-based retrodirective array architectures by measuring the phase difference between adjacent element pairs to increase array resolution. The transmit and receive frequencies are 2.45 and 2.4 GHz, respectively. Measurements demonstrate the ability to retrodirect to both single and multiple interrogators.
