Miniaturized Retrodirective Arrays for a Nanosatellite Platform [PDF]
, 2012 Abstract : A retrodirective antenna array (RDA) is capable of autonomously steering its radiation pattern toward the source of an interrogating signal, without having prior knowledge of the interrogator location. Integrating an RDA into a mobile platform, such as a nanosatellite, presents unique challenges due to the platform's restrictions in terms of

Large Active Retrodirective Arrays for Space Applications [PDF]
, 1978 An active retrodirective array (ARA) electronically points a microwave beam back at the apparent source of an incident pilot signal. Retrodirectivity is the result of phase conjugation of the pilot signal received by each element of the array.

Phase conjugator for active retrodirective arrayapplications
Electronics Letters, 2000 A novel phase conjugator for active retrodirective array applications is presented. The circuit provides conversion gain as well as phase conjugating operation by using active devices, and results in a simple and compact design through the use of a common port for RF and IF signals.
