Different types of radar systems are developed to serve specific applications such as surveillance, fire control, air-defense tracking, missile guidance, and low probability of intercept (LPI) operations. Each type utilizes a distinct set of pulse and frequency parameters, shaped by its operational requirements. To simulate these diverse radar types for testing and evaluation purposes, programmable radar simulators are employed. Effective radar simulation requires the generation of radar signals with configurable waveform parameters, such as pulse width, bandwidth, modulation, PRF, power, and frequency, to accurately replicate different radar emitters. In this paper, architecture of a programmable radar waveform generator based on a DDS-PLL hybrid design, intended for use in radar simulation systems is presented.
