Abstract: An environmental detection method for a vehicle uses transmitting antennas to emit transmission signals that each consist of a sequence of identical or similar single signals, uses receiving antennas to receive the transmission signals reflected from objects, and processes the received signals. The transmission signals are emitted from only one transmitting antenna at a time, and the active transmitting antenna alternates cyclically from single signal to signal. All receiving antennas are always used in parallel. The received single signals are accumulated in proper phase for the different combinations of transmitting and receiving antennas to at least one relative speed hypothesis of objects. Digital beam formation is performed based on the accumulated signal values, each belonging to the same relative speed hypothesis, from different antenna combinations. Phase differences between received signals from different transmitting antennas are thereby taken into consideration.

Abstract: A secure wireless transceiver, such as a link 16 transceiver, receives signals using an antenna array having an SOC associated with each antenna element in the array. The SOC's digitize and channelize received data for transmission to a message nulling system that mitigates jamming. The antenna array can be conformal, and can replace an existing Link 16 blade. The disclosed transceiver can be a modified CMN-4 transceiver with digitizing and channelizing moved to the SoC's, and replaced by the nulling system. The transceiver uses applicable TRANSEC information to assign received data to the logical Link 16 channels before nulling, and embodiments apply nulling only to channels of interest, thereby improving the nulling and reducing side lobes. Embodiments distinguish between desired and unwanted signals based on known Link 16 signal features and/or situational awareness, rather than signal amplitudes, thereby enabling nulling of even weak jamming signals.
