Abstract : The Randle Cliff Radar uses two radar systems, one operating at vhf and the other at uhf. These two radars are often operated concurrently so that data can be obtained on a target simultaneously at two frequencies. To permit simultaneous operation of the radars at different pulse repetition frequencies (prf) and different pulse lengths, a common synchronized timing system is required. This timing system, termed the radar synchronizer, provides the radars with properly timed triggers and gates for a variety of functions. This report describes the design and operation of the synchronizer which has been built and tested. It was installed in the radar system in October 1969 and consists of four rack-mounted units using solid-state discrete component and integrated circuitry. Simultaneous operation of the radars at different prf's and pulse lengths is provided, with the prf's synchronized. (Author)
