Abstract: | Channelized digital receiver is a more excellence EW receiver.Ghost signal in adjoin channel can be eliminated by instant frequency measurement technology,the disadvantage of fixed threshold detecting can be overcome by no-coherence cumulating technology,and channel striding for broadband signal can be solved by re-filtering technology.The validities of these methods are proved by simulation experiments,and the channelized digital receiver can be practical by these technologies. |

Keywords: | digital receiver instant frequency no-coherence cumulating re-filtering |
