Design and implementation of an airborne station frequency hopping synthesizer
Song Jia-yo · Microcomputer Information · 2009
Considering the detection requirement of the airborne station and the characteristics of stimulation and response signals, a frequency hopping signal generator based on FPGA is designed, in which digital frequency synthesis is implemented by AD9850 and MC145152. The hardware block diagram and principle are introduced. The software programmed in VHDL for each module is described in detail. And then, the program is simulated in QuartusⅡ7.0 and configured into FPGA. The result shows that requirement is achieved and the Frequency can hop in the range of all band of 45.5MHz.
