The Study Of Digital Signal Processing Module In Virtual Instrument Of Balistic Velocity Measurement With Doppler Radar

In this paper, the Doppler signed of cartridge velocity, that is produced by the Doppler radar, is taken as the research object. The characteristics of the Doppler signal of several kinds of cartridges are analyzed. The Spectrum analysis method is used to measure the velocity of several kinds of cartridges, based on Digital Data Processing technology and computer graphic technology. A new method of measuring the rotation rate of cartridges is established to improve the precision of measurement of cartridge rotation rate by a long way. A modularized weapon testing system is established based on the concept of Virtual Instrument that the software is the instrument. The graphical software testing flat is realized .The development of test project management module, data sampling module, spectrum analyzing module and cartridge velocity & rotation rate test module is accomplished.
