ABSTRACT:
The retrodirective array antenna of the present invention employs a circular, focusing parallel plate lens to interconnect array elements, thus producing a body with an inherently large radar cross section. By modulating the radiated signal from such an array, it is possible to meet the requirements for passive beacon and data transmission applications. Information transmittal is accomplished via the selection of the modulation function.
