| Abstract(in English) | The received signals of the passive sensor include noise and radio waves from multiple sources. Moreover, some radio waves change its frequency discontinuously (discontinuous waves) in time, so that these waves can not be classified based on the similarity of frequency as conventionally used. For that purpose, we had proposed a deinterleaving algorithm based on MHT (Multiple Hypothesis Testing) which are used for deinterleaving radar pulse train. In the conventional algorithm, the hypotheses are evaluated by the periodicity of time of arrival and the similarity of duration of call. However, the correlation between above two attributes was not considered. In this paper, we derived two-dimensional distribution of time interval of arrival and duration of call, and propose a MHT algorithm evaluating hypothesis by derived distribution. Furthermore, we evaluated the performance of the proposed method by the computer simulation. Consequently, as compared with the conventional method, the rate of correct classification has improved up to five points. |
