![]() 2018 also saw replacement radars at Foxwarren MB, Timmins ON ( near Smooth Rock Falls), and Spirit River AB and 19 of the new radars were in place by the end of 2020 with the rest being replaced sequentially by 2023. An additional radar will be installed in the Lower Athabasca region in Alberta. In June 2021, to ensure continuity of radar coverage in some areas while radars are being replaced, several of the radars had their ranges extended to 400 km (250 mi) in the lowest angle of reflectivity data. Such areas include the Edmonton area and the southwestern region of Newfoundland. ![]() Uses a klystron to produce a wavelength signal of 10 cm.Doppler since 1993 and dual polarization was added in 1999.This research radar is essentially a WSR-98A (see below) upgraded with dual polarization capability in 2004.The existing radars have antennas from two manufacturers: Enterprise Electronics Corporation (EEC) and Raytheon.some of the existing radars 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.Process received reflectivity and Doppler data with Sigmet Radar Data Systems, now a part of Vaisala Oyj.Each radar in the network will thus be called a WSR-98E, WSR-98R or WSR-98A for Weather Surveillance Radar - 19 98 (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 metres in diameter for the pre-1998 vintage radars and 6.1 m for the new ones.Pulse length and pulse repetition frequency adjustable. ![]()
