Introduction
Advances in RF and microwave communication technology 
have extended system performance to levels previously 
unattainable. 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.
