| The radio fuze signals have high modulation frequency, wide bandwidth. In order to discover radio fuze signals with a reconnaissance receiver of the jammer of radio fuze, bandwidth must be narrow and be less than signals bandwidth. The paper presents recognition method of radio fuze signals modulation under the situation.In order to design recognition methods of radio fuze signals modulation types. The paper, first of all, presents basic frame of recognition methods of signals modulation types and then, the paper introduces two recognition methods in the basis of decision theory and artificial neural network in detail, based on which recognition methods of radio fuze signals modulation types is designed in accordance with decision theory and the performance is simulated. At last, the algorithm is realized by devices selection, hardware circuit design, software flow design, frequency conversion realization in digital, module modulation and performance test.Recognition method of radio fuze signals modulation types discussed in the paper can promptly recognize signals modulation types in common used systems of radio fuze and can be used in the jammer of radio fuze and is essential premise to realize effective deception jamming. |
