The Design And Implementation Of AWG Radar Jamming Waveform Generation And Output Module

With the development of modern technology science, the applications of radarjamming technology in electronic warfare are more and more important. AWG radarjamming technology develops fast in recent years which combines high-speed digitalcircuits with digital signal processing technology. According to AWG jammingtechnique this dissertation designs and implements the AWG radar jamming waveformgeneration and output module.This dissertation first introduces the principle of AWG jamming waveformgeneration and then simulates the jamming signal waveform in Matlab and analysesthe results. Secondly it designs and implements the AWG radar jamming waveformgeneration and output module on the DSP and FPGA. Through the AD9735registersconfiguration controlling and phase calibration, it implements2DAs to sends accurateorthogonal jamming waveform. Finally, through the dual-port RAM and the LVDSmodules it implements the high-speed data transmission function and sends the AWGjamming waveform to DAC circuit in640Mbps data rate.The dissertation measures the output waveform of the system and analyzes theresults by the oscilloscope. The results of the dissertation have been applied to a radarreconnaissance and jamming system and passed the test verification.
