Abstract
The present disclosure relates to the technical field of solid engine burning rate test, and provides a method and system for measuring the burning rate of a propellant based on multi-channel ultrasonic waves. The method includes the following steps: collecting echo signals and corresponding noise signals of each ultrasonic channel, and pre-processing same; and finding a period of two adjacent echoes with the maximum amplitude difference, and the maximum peak of an echo period of current frame. In the present disclosure, the accuracy of echo moment is improved, and the burning rate is accurately measured under high noise environment.
