GPS Self-Calibration Apparatus of Beam Forming GPS Anti-Jamming System and Method Thereof

摘要

Embodiments of the present invention provide a GPS anti-jamming system, up-converting a frequency of a directly generated PRN code, using one antenna selected from a plurality of antennas to irradiate a GPS signal, and correlating the PRN code received from each channel to measure each time delay, thereby correcting a phase, delay, and size of a channel indoors within few seconds without separate calibration equipment.
