Design emphasis on sensitivity and selectivity  have resulted in dramatic improvements in those areas.  However, as factors previously limiting system performance have been overcome, new limitations arise and certain parameters take on increased importance. One of  these parameters is the phase noise of signal sources  used in pulsed RF and microwave systems. In pulsed radar systems, for example, the phase noise of  the receiver local oscillator sets the minimum signal level  that must be returned from a target in order to be detectable. In this case, phase noise affects the selectivity of the  radar receiver which in turn determines the effective range  of the overall system. Since the overall dynamic range of the radar system is  influenced by the noise of the transmitted signal, it is not  only important to know the absolute noise of individual  oscillators but to know the residual or additive noise of  signal processing devices like power amplifiers and pulse  modulators. Because the final signal in most radar systems  is pulsed, making absolute phase noise measurements on  the pulsed carrier is essential to determining the overall  performance of the system.
