Abstract :
The precipitation radar work carried out at Ottawa, Ontario, by the National Research Council of Canada (NRC), using dual-channel circularly-polarized radars, is described. This work, and concurrent work by NRC on weather clutter suppression for centimeter-wavelength military radars, included both theory and equipment developments. The discussion covers the early years (1956-66), the NRC Ku-band precipitation radar (1966-80), apparatus built and operated by NRC for scattering-matrix measurements, the NRC X-band precipitation radar (1981-6), and polarization switching and rotation studies.<>
