Abstract：A location method based on compressive sensing about multi radiation source is proposed,which can accurately estimate the number of the unknown multiple radiation sources and locate them.In this method,the field strength values are obtained in the partial position of the determined region by mobile monitoring.Due to the spatial sparsity of the target source,the compressive sensing method combined with the propagation model is used for coarse location after the preprocessing of the field strength value.In this way,the number of unknown radiation sources in the region is reconstructed with less field strength values.On this basis,in order to improve the positioning accuracy,genetic algorithm is used to locate the position of the radiation source in second positioning.Through the simulation and experimental verification of the algorithm,it is proved that the method is effective.
