Based on the analysis on the position of Electromagnetic Spectrum monitoring net emission source and the characteris-tics of TDOA,the flow of Joint TDOA location is introduced. The Chan algorithm,the joint Chan-Taylor algorithm and the improvement on location by particle filter are analyzed and simulated. After comparing the results of simulation,a joint location method based on spec-trum monitoring data,combining Chan-Taylor algorithm and particle filtering,is put forward. This joint location method can utilize effec-tively monitoring data from nodes in electromagnetic spectrum net,improving the location precision against target signals.
