Abstract
A radio detection and ranging (RADAR) sensor system signal generator is disclosed. The signal generator includes a lower frequency oscillator circuit to generate a first reference signal having a first frequency, a higher frequency oscillator circuit to generate a second reference signal having a second frequency that is higher than the first frequency, a set of frequency multipliers and signal mixers coupled to receive the first reference signal and the second reference signal, the set of frequency multipliers and signal mixers to generate a plurality of baseline signals, voltage-to-frequency converters to generate radar frequency waveforms at a plurality of specified frequencies according to chirp parameters for a plurality of frequency bands, and modulating radio frequency mixers to mix the plurality of baseline signals with the radar frequency waveforms at the plurality of specified frequencies to generate a multifrequency wavelet RADAR waveform.
