Experimental approach of FMCW signal generation using Direct Digital Synthesizer module

摘要

In this paper, the process of generating a signal frequency modulated continuous wave (FMCW) using direct digital synthesizer (DDS) will be presented starting from the design process simulation using the software on the computer until the realization and measurement of the generation of such signals on a module DDS, the kits from Analog Devices. Generation conducted a baseband signal with a bandwidth of 50 MHz in the frequency range of 50–100 MHz, the output power generated from −3.90 up to −7.80 dBm. FMCW signal is raised using Chirp waveform with the reference clock of 30 MHz and can be applied as a signal generator on the system Radar.
