Characteristics
- McGill radar (at the J. S. Marshall Radar Observatory):
- 9 metre (30 feet) diameter antenna.
- Using a klystron to produce a wavelength signal of 10 cm. (S-Band)
- Doppler since 1993 and dual polarization was added in 1999.
- The rest of the network :
- The upgraded radar have antennas from two manufacturers: Enterprise Electronics Corporation (EEC) and Raytheon.
- The new radar have antennas produced by Andrew Canada. With a diameter almost double the old ones; resolutions improved by the same amount.
- Use 5.6 cm wavelength emitting magnetrons. (C-Band)
- Process received reflectivity and Doppler data with Sigmet Radar Data Systems.
- Each radar in the network will thus be called a WSR-98E, WSR-98R or WSR-98A for Weather Surveillance Radar - 1998 (for the year of the start of the program) and the first letter of the manufacturer of the Pedestal/Antenna (Enterprise, Raytheon or Andrew).
- Antennas of 3.6 meters in diameters for the ungraded radars and 6.1 m for the new ones.
- Pulse length and pulse repetition frequency adjustable. Pulse length 0.8,1.6 and 2.0s. Pulse repetition frequency (PRF) 250 Hz and Dual PRF (Doppler Mode) 1190/1200 Hz.
