A Number Estimation and Location Method of Multiple Radiation Sources Based on Compressive Sensing[J]. Acta Electronica Sinica, 2018, 46(5): 1173-1178. DOI: 10.3969/j.issn.0372-2112.2018.05.023.
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
