Applying Dynamic Time Warping Algorithm to Specific Radar Emitter Identification

Nowadays, much attention of the study in electronic warfare research is paid to the specific radar emitter identification which is a key subject in the field. The individual differences of the radar emitters are generated due to the subtle differences of the internal components. At the same time, the individual differences can be well reflected by instantaneous amplitude and frequency. Regarding the condition, Dynamic time warping (DTW) algorithm is chosen to realize the distance measure. Data fusion technique is dropped in to achieve the target matching in the specific radar emitter identification, while the DTW measurements of the instantaneous amplitude and frequency are considered comprehensively either. Finally, the feasibility of the algorithm is validated through the simulation.
