Interior Ballistic Measurement: PXI-based Microwave Interferometer Design

摘要

A PXI-based microwave interferometer system is constructed to measure the velocity of interior ballistic ammunition. The hardware and software structure of the system is introduced. Wavelet denoising and polynomial chirplet transform is used to process motion signals. Finally, experiments are conducted aiming at the launching process of a certain object, and results show that the proposed system is of high efficiency to calculate the velocity-time, displacement-time and acceleration-time curve of the ammunition. As an experimental case study, the proposed system has been applied to interior ballistic measurement.
