ABSTRACT:
A radar transmitter is shown to include a voltage-controlled oscillator and associated amplifier to produce a signal to be transmitted with any noise generated within such oscillator and amplifier being reduced to a minimum by extracting a sample of the signal to be transmitted, downconverting such sample and then phase detecting the downconverted sample to derive a control signal for such oscillator.
