LARK SP-1M Radar Equipment NRL Prototype for ANA/MPQ 5 and ANA/SPQ-2 Radars NRL report 3584, Volume 1

This report describes the Lark SP-1M and its development. When the project was initially undertaken a primary requirement for the equipment was that it be capable of providing the guidance intelligence necessary for beam rider flight of the Lark missile. This was to be accomplished without compromise of the search and fighter control capabilities of the SP Radar. In its present form the Lark SP-1M Radar equipment is designed to serve as surface instrumentation for general purpose use in the control and evaluation of short range anti-aircraft guided missiles, having performance capabilities up to and including those of the V-2 rocket.
