| Abstract: | This paper presents a new analysis method WVD, which is used to analyze the periodic modulation signature, based on the parameter modeling of modulation in air-defense radar echoes. The modulated echoes of the aircraft rotating structures are simulated and analyzed under different noises. The results indicate that WVD is an effective way of analyzing and processing the periodic modulation signature of the rotating structures of helicopters. |
