<p>PROBLEM TO BE SOLVED: To solve the problem that it is difficult to accurately interpolate data when a weather target having a radar reflectivity factor generally varied according to a temperature profile, etc., of the atmosphere is observed since data between sweep lines are interpolated by using a received power value at the same distance from a radar in a conventional data interpolation method.SOLUTION: The radar apparatus selects observational data on the basis of a temperature profile, etc., of the atmosphere without limiting to observational data at the same distance from a radar to perform interpolation processing, and selects observational data by the temperature profile, etc., of the atmosphere after different weights are applied between different frequencies when the radar transmits and receives radio waves having a plurality of frequency bands, to perform interpolation processing.</p> |
