Abstract: In an exemplary embodiment, an RF device includes a receiver and an antenna. The antenna is configured to receive a reflected radio-frequency signal containing a set of modulated signal segments. Each modulated signal segment has a unique modulation pattern that indicates a time-variant reflectivity characteristic of a respective signal reflecting tile of a radio-frequency signal reflector. The receiver can include a circuit to process the modulated signal segments and determine a spatial intensity distribution of the radio-frequency signal incident upon the radio-frequency signal reflector. The spatial intensity distribution can be used by the circuit to determine a spatial radiation characteristic of an RF signal that is transmitted by a transmitter in order to produce the reflected radio-frequency signal. The transmitter, which can be incorporated into the RF device, includes a beam steering circuit that can modify a spatial radiation characteristic of the transmitted RF signal for addressing a misalignment.
