The active jammer, which is used in missile, is significant in breaking through enemy’s radar system. If the main part of jammer uses the new DSP (Digital Signal Processing) technology, the jammer can realize more flexible and more various jamming algorithm. Just because of this application foreground, the study of the module about data acquisition, processing and replaying is put forward.First, according to the request of jammer’s application, the thesis studies the functions of this module. Second, we study and plan the realization of all parts of the module’s functions. Third, we use impedance-matching differential line to solve the problem of crosstalk and reflection in high-speed signal transfer; To solve the place and routing problems in small PCB (Printed Circuit Board), we use some methods, such as the place-optimizing method, the rule-driving routing method; The basic signal-delay jamming algorithm and the circuit of module initialization are realized by using FPGA (Field Programmable Gate Array) technology. Lastly, we realize and test the module.In a word, the module’s realization gives us a way to solve the contradiction that the bandwidth of the digital jammer in existence is not in accord with the bandwidth of radar’s signal.At last, the paper summarizes the content and points out the further study emphases and direction.
