Abstract: The present invention presents a network apparatus and a selective information monitoring method using the network apparatus, which allow a user to monitor only required information (the field information of packets) from all received packets. The network apparatus one or more physical interfaces connected to a monitoring target host and configured to receive network packets from the monitoring target host, and a switch fabric module including a configurable monitoring module configured to perform filtering so that selective information is extracted from the network packets collected through the one or more physical interfaces.

Abstract: An anti-jamming apparatus and method for a compact array antenna are provided. The anti-jamming apparatus for a compact array antenna includes a Global Navigation Satellite System (GNSS) array antenna unit including a plurality of GNSS antennas for receiving GNSS signals transmitted from a satellite. A first beam-forming unit includes a plurality of combination units for receiving respective signals received by the plurality of GNSS antennas as a first reference signal and first auxiliary signals and combining the first reference signal with the first auxiliary signals, thus forming different beams. A second beam-forming unit receives signals of the different beams, and combining the signals of the different beams, thus forming an anti-jamming beam in which an invisible area is minimized.
