摘要： PROBLEM TO BE SOLVED: To solve the problem wherein an outrigger for maintaining horizontal level and a dedicated equipment for acquiring exact direction during operating weather radar, are required so as to operate a weather radar. SOLUTION: The azimuthal angle and elevation angle correction means of a weather radar consists of: an elevation angle inclination correction table creating means creating an elevation angle inclination correction table from a clinometer measuring tilt angle and departure between a machine shaft and an electric shaft of an antenna; a true azimuth initial value calculating means calculating a true azimuth initial value from magnetic deviation information or magnetic influence from magnetic direction and peripheral devices due to a magnetic compass; a solar azimuthal angle calculating means and a solar elevation angle calculating means calculating solar azimuthal angle and solar elevation angle based on the position obtained from GPS receiver and time information; a true azimuth correction value calculating means measuring solar noise due to an antenna the scanning domain of which is defined to calculate a true azimuth correction value; and a magnetic deviation information updating means updating the difference between the true azimuth correction value obtained from the aforementioned true azimuth correction value calculating means and the aforementioned true azimuth initial value as the aforementioned magnetic deviation information.
