Detection of periodic FM radiosignals with use of the conjugate coordinated filter

摘要

The possibility of suppression of correlation noise in the traditional detection circuits of FM radioimpulses packs is considered, at the expense of substitution of the coordinated filter with a code sequence by the filter coordinated with the conjugate code. The block diagrams detectors of completely known signal, signal with a unknown initial phase and amplitude are reduced. The overall detection performance are analyzed.
