The provided is an anti-jamming processing architecture based on a dual-component fusion application of a satellite navigation signal. The anti-jamming processing architecture includes: a receiver matched reception module, configured to receive a satellite navigation signal and separate the satellite navigation signal into a pilot component and a data component; a data channel anti-jamming module, configured to design a filtering weight vector recursive formula and perform anti-jamming on the received data component based on an updated filtering weight vector; a pilot channel anti-jamming module, configured to design a filter weight update formula and perform anti-jamming on the received pilot component based on an updated filter weight; and a data fusion application module, configured to perform message solving and pseudocode ranging respectively based on an anti-jamming data component and pilot component, fuse a pseudocode ranging result and solved message information, and provide a fusion result for a user.
