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

摘要

The present invention relates to a beam forming 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 a spoof; 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; By comprising: a navigation calculator generating the satellite direction information of the tracking satellite through calculation; 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.
