A new method for electromagnetic radiation source identification on the basis of directional characteristics
The directional characteristics of radiation source can be expressed by electric field distribution around them. Since the directional characteristics are unique parameters, they are applied for radiation source identification. Three basic radiated antenna models are analyzed, and cube receivers are utilized to collect the electric field distribution around them in the far field. Based on the data collected by cube receivers, the support vector machine (SVM) is used for radiation source identification, and then the evaluation model is established for accuracy analysis. The result shows that this method has high identification accuracy. Finally, the influence, from additive noise, scaling method and F1 measure are analyzed.
