摘要: The invention discloses a satellite navigation receiver multi-interference suppression method based on time domain group processing, which belongs to the field of RF interference suppression. comprises steps of: acquiring received signal data N channels by using an N-element antenna array; estimating period each periodic component in signals adopting improved singular value ratio spectrum method, and then calculating minimal common all components; regrouping pointshaving same frequency characteristics according estimated information, so as obtain new sub space-time matrix; completing interferenceelimination processing algorithm minimum power distortionless criterion; reconstructing after elimination obtaina required for subsequent processing. can increase number broadband frequency-modulation interferences resisted areceiver time-frequency sparsity generalized without increasing array elements receiver.
