Abstract
This paper describes the new techniques to estimate the phase noise requirements of STALO for a Doppler radar application. The power spectral density of frequency modulation is derived from the phase noise characteristics of oscillator to be applied in Doppler radar systems and then the Doppler aperture function is calculated according to a signal transit time and half-power bandwidth of Doppler filter. Finally, sideband noise level of this IF signal spectrum is compared with system conditions.
