Abstract : A digital antenna pattern generator for producing an electrical signal to simulate any desired antenna pattern for which the device has been preprogrammed. Read only memories are utilized which are preset according to applicable intelligence data to read out desired radar antenna patterns as the memory locations are addressed in seriatim. In the preferred embodiment of the invention, the read only memories are sequentially addressed in accordance with the angular displacement across the antenna beam pattern. In an alternative embodiment, a free-running antenna pattern generator is disclosed in which the beam width, dead time and lobe rate is adjusted. Both systems convert the digital pattern generated by the read only memories into an appropriate output analog signal. (Author)
