发明名称 System and method for detecting broadband global positioning system (GPS) jamming
摘要 A system and method for detecting broadband global positioning system (GPS) jamming is provided, the system including a local oscillator maintainer to maintain a plurality of local oscillators, a frequency band selector to select a frequency band in which jamming is to be detected, in response to receipt of a radio frequency (RF) signal, an oscillating signal output unit to allow an oscillating signal to be output from a local oscillator identified based on the selected frequency band, among the plurality of local oscillators, and an intermediate frequency (IF) signal generator to generate an IF signal using the RF signal and the oscillating signal.

主权项 1. A system for detecting global positioning system (GPS) jamming, the system comprising: a local oscillator maintainer to maintain a plurality of local oscillators; a frequency band selector to select a frequency band in which jamming is to be detected, in response to receipt of a radio frequency (RF) signal; an oscillating signal output unit to allow an oscillating signal to be output from a local oscillator, which is identified based on the selected frequency band, among the plurality of local oscillators; and an intermediate frequency (IF) signal generator to generate an IF signal using the RF signal and the oscillating signal, wherein the local oscillator maintainer sets lengths of periods with respect to the plurality of local oscillators to differ from each other, based on an external command.
