By an integrated data processor is meant a -unit which accepts infor mation from a search radar and supplies digital coordinates of targets seen by the radar to data relay equipment» This report discusses an integrated data processor for particular radar and data relay equipment so that minor changes would be necessary with other equipments* FUNCTIONS The integrated data processor has several functions, in the sense that the input information is operated upon serially, in several ways« These functions ares 1« MTI by delay line cancellation« 2« Noise reduction by video sweep integration« 3« Beamsplitting (target azimuth determination within less than a beamwidth)« lu Signal strength measurement« 5« Conversion of target data to Cartesian coordinates (including translation of origin)o 6« Buffer storage of digital target coordinates from several beamwidths and the synchronous output of these upon demand of relaying equipment« STORAGE One fused quartz delay line is used as the storage unit for the various functions« Two FM channels are used for MPI and video integration« One FM or five AM channels are used for bearnsplitting, one AM channel is used for signal strength and three AM channels are used for buffer storage« Bandwidth requirements are estimated in the appendix*
