"An historical account of a DRB developed doppler spectrum tracker for the first Canadian lightweight doppler radar is provided for archival purposes. A system for tracking the doppler frequency spectrum from an airborne navigation radar is described. The tracker provides a continuous analogue output for ground speeds between 50 and 1,000 knots. Integrated ground speed is also provided in digital form. The precision of both measurements is within one-half per cent over a complete environmental range of operation. The system was used successfully in the production models of the AN/APN 147 and the CMA 623 radars. These radars were the first of a series of lightweight airborne doppler navigation systems developed in Canada"--Abstract, page 1. Issued also in print format. Doppler radar. Radar Doppler.
