Abstract

A low phase noise radar system is disclosed. The system has a signal generator having a stable oscillator that outputs a first lower-frequency signal, a direct digital synthesis circuit that outputs an analog waveform, and a mixer to receive the first lower-frequency signal, and the analog waveform, the mixer to mix the first lower-frequency signal and the analog waveform to generate a signal generator output signal. The system further includes an up converter coupled with the signal generator to filter and to increase frequencies of the signal generator output signal to generate a filtered and frequency multiplied signal to be transmitted.
