The Research And Realization Of The Reconnaissance And Jamming For The Communication Of Military Frequency Hopping Transceiver

This paper is written on the basis of work of the university's scientific item. And the item's name is"the experiment of the Reconnaissance and Jamming for Ultra-short Frequency Hopping Communication". The experiment is used to show the theory of Frequency Hopping Communication, the methods of reconnaissance and jamming for Hopping Frequency communication and the difference in all kinds of jamming methods. In this paper, the fundamental theory of Frequency Hopping Communication is introduced first, and some problems met in the Electron Reconnaissance with the progress of Frequency Hopping Communication are introduced at the beginning. The paper gives a kind of FFT Channelizing scheme used in the item, by analyzing different methods of reconnaissance and jamming for Hopping Frequency communication. And the paper gives a kind of design of Frequency Synthesis System on the basis of FPGA and DDS technology, and FPGA is used to control the DDS chip to produce different jamming signal. In the design of the system, the USB technology which is used widely is inducted in the control module. The paper gives the realization of the control of choosing of the methods of Electronic Jamming through USB by the computer. In the end, the paper introduces some experience and lessons met in the design and debugging of the software and hardware, and a summarization of the work of this paper is given.
