Design of the Intermediate Frequency Simulator for a Terminal Homing Radar Based on DDS
Baixiao Chen · Guidance and Fuze · 2008
The method of FPGA and two-channel DDS is used in this paper to design the intermediate frequency simulator,which is used in terminal homing radar.The IF simulator can generate different kinds of modulated signals with different duration,different time bandwidth,different frequency bandwidth,it can dynamicly simulate sum or difference of single-pulsed signal under the inner or the external synchronization,it can also simulate servo system under different mode.The practice results have proved its excellence of pure frequency spectrum,high stabilization,and flexibility to use.This simulator is successfully used in the design and debug of signal processors in many types of terminal homing radar.
