<P>PROBLEM TO BE SOLVED: To provide an electromagnetic interference detection device that is able to accurately detect an interference wave. <P>SOLUTION: A reception radio wave waveform acquisition unit 101 receives a communication signal with a prescribed frequency, a feature amount calculation unit 102 calculates at least one amplitude feature amount based on a result acquiring temporal waveform data of the communication signal as sampling data at every prescribed clock time, and a similarity calculation unit 103 calculates respective similarity with multiple pieces of teacher data for the calculated amplitude feature amount at every prescribed clock time. Furthermore, an interference detection parameter calculation unit 105 performs comparison calculation of similarity with the multiple pieces of teacher data to derive an interference detection parameter for electromagnetic interference detection, and an electromagnetic interference determination unit 106 compares the interference detection parameter with a prescribed threshold value to determine whether there is occurrence of electromagnetic interference or not, and output unit 107 outputs the determined result. Here, a memory unit 103 stores the amplitude feature amount, the similarity, the teacher data, and the determined result of electromagnetic interference occurrence. <P>COPYRIGHT: (C)2013,JPO&INPIT |
