A phase noise test system of pulse modulated millimeter wave amplification chain

This paper introduces the influences of phase noise to radar systems. The measurement of phase noise in pulse modulated carrier is one of the most important tech- niques. The paper gives the principle and technical norms of the phase noise measurement system. It also gives how to develop the parts of the measurement system. A special method to calibrate the phase noise measurement system is introduced. The measurement system is very easy and accurate for the engineering measurement.
