Research On Data Acquisition And Processing Technology Of Radio Fuz

Radio fuze is widely used in various air-to-air missiles and air defense missiles due to its outstanding advantages of strong anti-interference ability and high burst point control accuracy.The study of the algorithm is inseparable from the verification of large amounts of data.In the design and test of radio fuze,various analog and discrete signals need to be collected so that designers can analyze the working state and related parameters of radio fuze.In this thesis,the data acquisition and processing technology of radio fuze is studied.The main work is as follows :Based on the working principle of Doppler radio fuze,the echo signal characteristics of radio fuze are analyzed,and the synchronous acquisition of Doppler echo signal and 8-channel discrete signal of dual radio fuze is realized.The large capacity non-volatile storage of collected data is realized based on NAND Flash chip,and the upload of collected data is realized based on RJ45 network port,Wi Fi and serial port.The network port receiving host computer and serial port receiving host computer with state control,data receiving,data storage,data analysis and data curve drawing functions are designed.For a variety of analog and digital data acquisition equipment,the synchronous acquisition of multi-source data is studied,and the high-precision data synchronization based on multithreading is realized.The synchronization accuracy is analyzed and tested.The software and hardware tests of the radio fuze data acquisition system were completed,and the test results were analyzed.The functions and performance indexes of the radio fuze data acquisition system were verified.
