If Simulation Of Radar Jamming Signal Deception Based On FPGA

With the development of electronic science and technology as well as new radar system appeared storage technology based on digital radio and radar jamming radar echo simulation technology came into being.This paper presents a simulation-based digital radio technology radar echo simulation technology to store and radar signals of deception, and the formula radar echo signal generated by the control word derivation and calculation. FPGA-based, research-based DDS (Direct Digital Synthesizer) direct digital frequency synthesis signal generator, radar echo signal and deception jamming signals, for a certain type of radar simulator for the overall presentation, and to highlight the mechanisms which produce and process signals deceit, deception signals the main logic board module generates a detailed talk, then to deceive signal simulation study Modelsim, and a hardware implementation, viewed from the IF RF output signal on the oscilloscope showed that digital radio frequency memory technology is a very effective radar jamming signals generation techniques, and finally a conclusion based on the simulation and analysis of actual results on the oscilloscope display.The results show that radar-based store and forward mechanism of deception signals in the availability of resources, can be of different types of multi-objective deception as needed, and deception of such a mechanism and radar signals transmitted signal has a good coherent nature.
