PROBLEM TO BE SOLVED: To utilize an onboard beamformer in conjunction with ground-based signal processing to cope with interference, even in the presence of unknown reflector distortions.SOLUTION: A satellite 302 includes an onboard beamformer 328 (OBBF), a feed array 322 and feeder-link antenna 320. The OBBF is configured to produce first and second spot beams 330, 332 respectively for first and second geographic regions. The feed array is configured to receive first and second signals respectively in the first and second spot beams for respective geographic regions. At least portions of the first and second signals include communication data and interference causes, respectively. The feeder-link antenna is configured to transmit the first signals and second signals to a gateway station 304, and the gateway station includes a signal processor 316 that is configured to suppress any interference to at least a portion of the first signal including the communication data. |
