Extraction and Identification of Radar Emitter Individual Characteristics
Tao Chen · 2013
To solve the problem of radar emitter individual identification,we propose to use the wave shape entropy and energy entropy to extract characteristics from surrounding-line integral bispectrum estimate results, based on the 2D characteristic vector composed of the characteristics to identify radar emitter individuals. Then,to identify the 2D characteristic vector,we propose barycenter distance in analyzing the 2D characteristic vector in order to identify homologous radar emitter individuals,and compare it with the fuzzy C-mean clustering method.Computer simulation and experimental results verify the correctness and effectiveness of the proposed method in identifying radar emitter individuals at certain signal-to-noise ratio.
