The target simulator can help debug radar system and do operation training.In this paper,we adopt AD9857 to design a monopulse radar target simulator.By using digital intersection,we can obtain the operational parameters of DDS.Then the DDS directly produces the two channel IF (intermediate frequency) signals.We also propose continuous wave correcting and wave storage to solve the sign of the difference pattern.During the development of a radar,the validity of the simulator is validated.

Key words: monopulse;target simulate;amplitude-comparison angle measurement;sum and difference pattern
