Radio Specific Emitter Identification (SEI) is the technique which identifies the individual radio emitter based on the received signals' specific properties called signals' Radio Frequency Fingerprint (RFF). SEI is very significant for improving the security of wireless networks. A novel SEI method which treats the emitter as a nonlinear dynamical system(More)
This paper addresses the problem of direction-of-arrival (DOA) estimation of multiple wideband coherent chirp signals, and a new method is proposed. The new method is based on signal component analysis of the array output covariance, instead of the complicated time-frequency analysis used in previous literatures, and thus is more compact and effectively(More)
