Study on Acoustic Characteristics of Aircraft Targets' Propulsion System

Abstract:

For the short-range defensive weapons, extracting the acoustic characteristic of attacking aircraft at low altitude is an effective way to detect and recognize the target. The signal characteristics of radiated noise of the typical vehicle propulsion system are analyzed, and thus the signal models for propulsion system noise and for passive acoustic early-warning system are given. Finally, the analysis result of the measured aircraft noise validates the feasibility of the signal model.
