| Abstract: | A radar intermediate frequency simulator based on DDS chip AD9854 is introduced. The simulator uses the ADSP-BF532 processor as the core, the ADgS54ASQ frequency synthesis chip as target signal generator, and generates a group of analog intermediate frequency echo. The simulator can produce different modulation modes of radar intermediate fre- quency echo, such as general pulse, phase coding and LFM, and output a team of adder, subtract return wave. It can be applied to debugging and training of multi-kinds of new system tracking radar. |
