Research On The Key Technology Of Microwave Interferometer's Data Processing

Microwave interferometer can be used to measure the moving parameter of theprojectile in the life-weary taker, and is the important ensure of improving theperformance of the artillery and the projectile.This text synopsis introduces work principle and its design of microwave interference instrument, mainly is concerning many Pu leises to measure soon principle analysis, at analytical return to wave signal characteristic foundation up establishment related sport target time wave signal mathematics model. And use repeatedly analytical the method presumably acquire the moment frequency of signal and pass to adopt short time Fu to sign the theory principle that leaf's transformation and Wigner-Ville distribute and start to build up inside the basic model of ballistic target time wave signal.In addition, the system is soon used ARM and FPGA technique to carry out to measure radar terminal the control and data handle function, the project has to respond to in time, the function is strong and sex price compare a good characteristics. Pass the FFT function mold piece that the use expands a FPGA technique, SEP3203 the processors are systems core, set up into the hardware platform of built-in system signal processing;The first floor software platform adopted built-in Nucleus PLUS operate system to complete related drive the design of procedure. Emphasized to solve 3:00 in the research key technique, namelyrWith ARM processor for the hardware of core design;Nucleus PLUS the built-in operate system transplant SEP3203 in the processor;FFT drives program design.Pass to try to the mold's piece's adjusting with improvement to design, main function index sign and function of system a] 1 come to a the request of developing the task book.
