foe and ambiguity checking the radar signal generator apparatus utilizes a stored binary data word representing each simulated radar target trace and each data word contains bit fields for each of the above target features as well as the simulated target position on the radar display indicator a single counter driven by the radar system clock is used to generate binary numbers that are compared to the target position information of each stored target data word upon a comparison match the radar display writing beam is intensified to trace the simulated radar target with the trace width specified by the appropriate bit field of the associated data word application_number US 70865676 A description turning now to fig2 and 3 of the drawing to give a detailed description of my novel radar target generator in fig3 is seen scenario selector 319 which is used to assemble an almost infinite variety of training scenarios from files of individual target training scenario and terrain blanking which are stored in memory 322 an instructor utilizes selector 323 to instruct microprocessor 324 as to which individual target training scenario and terrain blanking files are to be read out of memory 322 and combined to produce a.
