Patent ID: 8169358

Claim:
A coherent multi-band RF transceiver for transmitting communications data and radar signals, the transceiver comprising: a) a transmitter comprising: i. a source of communications data and radar signals; ii. a modulator that is electrically connected to the source, the modulator modulating the communications data and radar signals with a carrier signal; iii. a synthesizer having an output that is electrically connected to a modulation input of the modulator, the synthesizer generating the carrier signal; and iv. a logic device that is electrically connected to a control input of the synthesizer and to a control input of the source, the logic device instructing the synthesizer to change the carrier frequency sequentially in time and instructing the source to provide communications data and radar signals corresponding to the changing carrier frequency so that multiple bands of communications data and radar signals are transmitted over a desired spectrum; and b) a receiver comprising: i. a demodulator that demodulates a received signal transmitted by the transmitter; ii. a synthesizer that is electrically connected to a control input of the demodulator, the synthesizer generating a signal that tunes the demodulator to a desired carrier frequency; and iii. a logic device that is electrically connected to a control input of the synthesizer, the logic device instructing the synthesizer to change the carrier frequency sequentially in time so that the demodulator demodulates the multiple bands of communications data and the radar signals over the desired spectrum.
