Frequency Agility Fm Fuze Difference Frequency Signal Digital Processing

Combine with the Digital signal processing technology this paper discuss the way to process the differential frequency signal which is come from frequency agility and freguency modulation fixd-distance fuze.On the base of researching the theory of the scheme and analyzing the signal feature it is obtained that the existence manners and character of distance information in the differential frequency signal. Aim at the signal feature and the system request of fixed-distance ascertain the principle of parameter choice. At the same time a new conclusion is gained that the digital signal processor can improve the precision of fixed-distance and stong ability of anti-interference.Especially in triangle modulation system the digital signal processing can compensate the error arose by Doppler frequency commendably.Design the hardware and compile the arithmetic to implement the system function. Associate the CCS and Matlab use the emluator and signal generator to debug the system.It is proved that the conclusion is exactitude and actable according to the processing result of system...
