Doppler radar systems are being used to provide specialized information about the world around us. Real-time processing of Doppler information is allowing for the prediction of severe weather, the determination of flight conditions at US airports and the defense of our country. But, as with any RF-based system, performance can be impaired by the destructive properties of phase noise. Phase noise can render a target undetectable, reduce a system's dynamic range and cause unique spectral anomalies to occur. Radar engineers involved in the design of coherent radar systems that use Doppler motion for target detection or who are tasked with the interpretation of Doppler data, ...
