A processor using a baseband c.c.d. data store and an i.f. s.a.w. chirp filter is shown to offer a realistic alternative to optical or digital s.l.a.r. processing. Range sorting and pulse averaging can be done within the store while the complex correlation for many range cells can be accomplished using a single s.a.w. filter.
