Title The technology of static interference experiment of
radar signal base on virtual instrument
【Abstract】 Based on the static interference experiments signal generation technology of analog instruments can simulate generate a variety of radar jamming in real-life,which can used to detect radar anti - interference capability.This thesis has analysis the form of common radar interference signal,and make a derivation analysis of signal characteristics.Simultaneously,understanding the use of RF signal processor made of NI company.Produce commonly used radar jamming signals based on labview software programming,then transmitting signals by RF signal processor.To verify the correctness of the transmitted signal,we observing and analyzing the transmitting signals by spectrum analyzer and oscilloscope..It makes the static interference signal generation technology which based on virtual instrument has a strong reference value in practical applications.
