Moving targets generally have both along track and range velocity components. The range component can move a target through many range cells over a long spotlight aperture for wideband fine resolution radars and this reduces the azimuth resolution. Analysis using a stationary phase method shows that the azimuth resolution is determined by the time taken by a target to move through a range resolution cell. An algorithm is developed which can, in principle, determine the horizontal components from changes in target blur width over the aperture.
