A system comprises a vehicle radar sensor including an antenna, transmitter, receiver, and processor. The processor hosts a scanning control module that sends a control signal to the transmitter, receiver, or both, to generate radar beams; and a signal processing module that receives a reflected signal from the receiver to generate radar data. The system also includes an onboard application module and ground surface database. The application module is operative to access information from the surface database, access position and attitude data, access position and attitude uncertainty data, access radar installation data, and access radar data from the signal processing module; identify ground surface areas to be avoided based on the information from the surface database, the position and attitude, the position and attitude uncertainty, and the radar installation data; and perform modified radar operations and/or processing when the ground surface areas to be avoided are within a radar FOV.

Smart radar altimeter beam control and processing using surface database

A plurality of antenna elements may receive a plurality of signals. Each of the plurality of antenna elements may correspond to at least one of a plurality of sectors of a sectorized antenna. A receiver may process each of the plurality of signals in parallel, including decoding one or more messages from the plurality of signals. The receiver may output at least one of the one or more messages.

Sectorized antennas for improved airborne reception of surveillance signals

In one example of this disclosure, two decoders perform a method for detecting and decoding overlapping radio surveillance signals. The first decoder detects a first automatic dependent surveillance-broadcast (ADS-B) preamble from a signal stream received via a front-end unit. The first decoder decodes the first ADS-B signal associated with the first ADS-B preamble. The second decoder detects a subsequent ADS-B preamble from the signal stream while the first decoder is decoding the first ADS-B signal. The second decoder decodes the subsequent ADS-B signal associated with the subsequent ADS-B preamble.
