AbstractThis report describes in general terms the design and performance of the first experimental model of the N.R.C. coherent pulse radar equipment. A line of these early warning stations across the north of Canada is visualized to relieve the load on the main defenence system. Two fixed, narrow azimuth, vertical fan beams are directed obliquely from each station in the fence, with an average station separation of 30 miles. Coherent pulse and integration techniques are used to distinguish moving targets from permanent echoes. The antenna pattern is 10° in azimuth and cosecant to 40,000 ft. The crystal-controlled transmitter emits 5 KM peak, 20μs pulses on 600 Mc. Automatic alarm of moving targets is provided with course range discrimination. No operator is needed but maintenance will be required. Ranges up to 70 miles have been obtained on random aircraft, although formal flight trials have not been carried out yet. Under moderate clutter conditions the system is stable, without false alarms, and operates on aircraft echoes 3 db above noise. In severe clutter the operation is not yet entirely satisfactory.
