Generating Precise FMCW and Chirp Radar Test Signals with Low-cost Devices

RF/microwave signal generators offering high speed frequency modulated continuous wave (FMCW) and frequency modulation on pulse (FMOP), or “chirp” capabilities, are depended on by radar system engineers in many fields. In particular, those designing microwave test sets for receivers in highly precise radar systems, such as anti-spoofing and anti-jamming applications. To achieve the reliable FMCW and chirp modulation necessary, one would typically rely on a full-featured bench-top unit.But many are discovering that today’s robust, portable, and programmable RF/microwave signal generators offer a real, low-cost, and flexible alternative. This Tech Brief provides insight on this self-managed approach and offers tips and tricks on how to get up and running fast and with confidence in every pulse.
