Retrodirective array augmentation for electronic RCS modification

, 2002
In this paper, an active Pon type retrodirective array (RDA) is augmented with a passive array in order to provide electronic modification of the transmit function of the combination in response to the influence of an external interrogating signal: By ...

Real component effects on PON retrodirective array performance

, 2001
We show how the positional accuracy of the re-transmitted signal from a PON retrodirective antenna array (RDA) is influenced by array size, array element type, LO phasing error, mixer leakage and conversion gain imbalance. Specific recommendations on the

An active subharmonic retrodirective array using dual polarized microstrip antennas [PDF]

, 2004
Retrodirective antenna arrays, when illuminated by an interrogator signal, transmit a signal back towards the interrogator in the same direction as the incoming signal, without any prior knowledge of the source direction.
