发明名称 Global Navigation Satellite System (GNSS) Anti-Interference using Array Processing
摘要 Embodiments of the invention are directed to GNSS anti-interference using array processing. In one embodiment, a device may be configured to receive signals GNSS signals. In one embodiment, the signals may include a superposition of GNSS signals from independent transmitter sources and a spoofing signal. The spoofing signal may include several pseudo random noise (PRN) codes originating from a single transmitter source. In a one embodiment, the device may include multiple radio frequency (RF) inputs connected to multiple antennas and may use a combining algorithm to produce a weighted sum of the antenna outputs. The resultant sum may be passed through an output port of the device that is configured to be coupled to an RF input port of a GNSS receiver.

主权项 1. An apparatus for spoofing countermeasures comprising: an input configured to receive a plurality of signals from an array of antenna elements; a processing unit coupled to the inputs and configured to pre-process the plurality of signals from the array of antenna elements with a combining for suppressing a spoofing component in the signals and generating a combined signal for further processing; and an output coupled to the processing unit and configured to provide the combined signal for further processing.
