BEAM FORMING ANTI-JAMMING PROCESSING APPARATUS CAPABLE OF ELIMINATING SPOOFING SIGNAL USING ARRAY ANTENNA

摘要

The present invention relates to a beamforming anti-jamming device capable of removing a spoof signal using an array antenna, an array antenna, a frequency down-converter for converting an RF satellite navigation signal received from the array antenna into a digital IF signal and outputting the spoofing A spoof signal direction jamming signal is generated by simulating a jamming signal based on the signal direction information, and a jamming signal is removed from the digital IF signal and the spoofing signal direction jamming signal based on the satellite direction information, and a beam is formed in the satellite direction. Interference signal processing means for outputting a signal from which the jamming is removed, and a correlation processing unit for determining whether or not to track a satellite, and for extracting correlation peak value information by reflecting a carrier wave and a code corresponding to a tracking satellite to the signal from which the jamming is removed; A navigation calculator generating the satellite direction information of the tracking satellite through calculation, and a spoof signal detecting unit receiving the satellite direction information and the correlation peak value information to detect a spoofing signal and outputting the spoofing signal direction information, It is possible to remove the spoofing signal by searching and detecting the omnidirectional signal, and it is possible to improve the navigation performance by minimizing the loss to the tracking satellite.
