The present disclosure relates to an apparatus and method for removing noise for a weather radar and, more particularly, to an apparatus and method for removing noise for a weather radar, the apparatus and method being able to detecting a radio interference echo, which is noise due to radio interference that is generated by reception of other external radio waves to a weather radar except for a radio wave transmitted from the weather radar, separately from weather eco according to normal weather measurement, and being able to remove the radio interference echo.

Apparatus and method for removing noise for weather radar

Provided are an apparatus and a method for removing noise for observation information of a weather radar, and more particularly, an apparatus and a method for removing noise for observation information of a weather radar capable of separating and removing second trip echoes corresponding to noise from precipitation echoes by simulating the reflectivity of the second trip echoes caused by a distance folding phenomenon shown in weather observation information generated using a weather radar. According to the present invention, in order to remove the second trip echo that occurs in the observation information measured in the volume observation radius during weather observation by setting the weather radar as the volume observation radius where the second trip echo occurs, the weather radar is set as a long-range observation radius in which a second trip echo exceeding the volume viewing radius does not occur.

Apparatus and method for removing noise for observation information of weather radar

An apparatus and a method for estimating rainfall of hail and rain using a dual-polarization weather radar improve accuracy of classification of hail and rain zones and estimation of rainfall intensity by classifying hail and rain zones using a distribution of horizontal reflectivity and differential reflectivity of radar observation values, discriminating between a convective zone and a stratiform zone depending on reflection intensity, and applying a dual-polarization-based rainfall estimating relational equation for each type in a weighted mean technique.
