| Abstract: | According to the problem that the triditional FM radio fuse could not detecet the range continuously,a time-frequency method was used to research theinstantaneous frequency estimating algorithms of difference-frequency signal for radio fuse.Based on Wigner-Ville Distribution,the characters of WVD maximal value algorithm,SPWVD maximal value algorithm and Viterbi-SPWVD algorithm on instantaneous frequency estimation were analyzed.Then the performances of the algorithms analyzed above were compared through Monte Carlor simulation,and the results of simulation was given. |
