Abstract
The report describes a method for computing the frequency source stability requirement for an airborne pulse-Doppler radar system. This method does not rely on restrictive assumptions about the range of Doppler shift extent of the ground clutter, and hence is applicable to situations where the antenna beamwidth is large relative to either or both of these parameters. Starting with information derived from an airborne radar simulator, general equations are developed which express bounds on the four main representations used to describe a frequency reference. These are the single sideband AM and PM noise power spectra, and the spurious AM and PM signal power levels. Bounds for each of these functions are determined so as to minimize their effect on the post-processing signal-to-interference ratio. The technique is specifically applied to determine the frequency source stability requirements for a radar transceiver to be constructed for Defence Research Establishment Ottawa. TRUNCATD
