System and method for interrogating a target using polarized waves
First Claim
1. A method for communicating, the method comprising:
- generating a first message by a processor;
controlling a beam steerer to deflect transmitted waves toward a spatial angle;
transmitting the first message through an antenna in communication with the beam steerer toward the spatial angle;
controlling the beam steerer to deflect waves received from the spatial angle; and
receiving a responsive wave at the antenna through the beam steerer at the spatial angle, the responsive wave including a second message responsive to the first message.

Abstract
A system and method for communication that could be used in an identification friend or foe system. The method comprises generating a first message by a processor and controlling a beam steerer to deflect transmitted waves toward a first angle. The method further comprises transmitting the first message through an antenna in communication with the beam steerer toward the spatial angle. The method further comprises controlling the beam steerer to deflect waves received from the spatial angle. The method further comprises receiving a responsive wave at the antenna through the beam steerer at the spatial angle, the responsive wave including a second message responsive to the first message.

8. A communication system, the system comprising:
-
a processor; an antenna in communication with the processor; and a beam steerer in communication with the antenna and the processor; wherein the processor is effective to generate a first message; generate a first control signal to control the beam steerer to deflect transmitted waves toward a spatial angle; cause the antenna to transmit the first message toward the spatial angle; generate a second control signal, distinct from the first control signal, to control the beam steerer to deflect waves received from the spatial angle; and receive from the antenna a second message in a responsive wave, the second message responsive to the first message and received by the beam steerer at the spatial angle. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A communication system, the system comprising:
-
a processor; a first antenna in communication with the processor; and a beam steerer in communication with the first antenna and the processor; wherein the processor is effective to generate a first message; generate a first control signal to control the beam steerer to deflect waves toward a spatial angle and to transmit waves polarized in a first polarization-direction toward the spatial angle by applying a first current to the beam steerer; cause the antenna to transmit the first message toward the spatial angle using waves circularly polarized in the first polarization-direction; a target, the target including a second antenna, the second antenna effective to receive the first message and transmit a responsive wave including a second message responsive to the first message, the responsive wave including waves circularly polarized in the first polarization-direction, the processor further effective to generate a second control signal, distinct from the first control signal, to control the beam steerer to deflect waves received from the spatial angle and to receive waves polarized in the first polarization-direction from the spatial angle by applying a second current to the beam steerer; and receive the second message from the first antenna. - View Dependent Claims (17, 18, 19, 20)
