Patent ID: 7298313

Claim:
A radar-compatible data link system comprising the combination of: radar signal transmitting means; radar signal return processing means, and a remotely-disposed radar signal receiving means: said transmitting means including: means for generating a fixed continuous wave carrier frequency, means for generating a plurality of differing pulse repetition frequencies (PRF'S) means for selectively modulating said fixed carrier frequency with said generated PRF's for producing transmitter output signal pulses having said fixed carrier frequency as a center frequency component and a sideband component formed by said selected PRF, a digital data source for introducing into the system said data link information, and means controlled by said digital information for repetitively selecting the modulating PRF; said return signal processing means including: means for processing said fixed carrier frequency component to produce radar-return information, and said remotely-disposed receiving means including: a matched band-pass filter for each of said PRF's, said filters each being adapted to pass as an output sideband components produced by a particular PRF generator, and differential amplifier means receivably coupled to said filter output for processing said filter means output for reconstructing said data link information whereby said system is capable of processing radar return data concurrently with the transmission of said digital data information.
