Abstract
Systems and methods for digitally synthesizing chirp signal in a low intermediate frequency (IF) band and using frequency multipliers to generate a higher frequency signal for radar applications are described. An embodiment includes a chirp signal generator that includes: a direct digital frequency synthesizer (DDFS) that is configured to receive an input sync signal and a frequency reference signal and generate several chirp signals at a first frequency that is in a low intermediate frequency (IF) band, several frequency multipliers that are configured to increase the chirp signals to higher frequencies and several bandpass filter circuits that are configured to remove nonlinearities from the chirp signals to generate a clean output signal.
