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

An apparatus for removing noise for observation information of a weather radar, the apparatus comprising:

• a setting unit for setting an observation radius of the weather radar;
• an observation information generation unit that generates first observation information based on a signal received from the weather radar with a set volume observation radius according to setting of the observation radius of the weather radar by the setting unit and generates second observation information based on a signal received from the weather radar in which a long-range observation radius exceeding the volume observation radius is set;
• a simulation unit that generates a simulation echo by applying a predetermined simulation algorithm for each observation echo out of the volume observation radius in the second observation information to simulate a second trip echo corresponding to the observation echo of the second observation information;
• and
• a control unit that determines and removes the observation echo corresponding to the simulation echo among the one or more observation echoes included in the first observation information as noise based on the simulation echo simulated through the simulation unit.
