This paper presents the simulation of a Direct Digital Synthesis (DDS)-based programmable radar waveform generator designed for radar simulator or configurable radar systems. The system enables flexible control of key radar signal parameters including carrier frequency, pulse width, and pulse repetition interval (PRI). DDS technology is leveraged to digitally generate high-precision waveforms with minimal latency and high spectral purity. Simulation results demonstrate the generation of a variety of radar waveforms under programmable settings, confirming the system’s capability to support multiple radar modes through digital reconfiguration. The proposed DDS-based architecture provides a cost-effective and scalable solution for modern radar waveform generation, particularly in software-defined and cognitive radar environments.
