WEATHER RADAR APPARATUS, OBSERVATION SEQUENCE GENERATION METHOD, AND OBSERVATION SEQUENCE GENERATION PROGRAM

摘要

According to one embodiment, a weather radar apparatus includes an antenna apparatus, a signal processing apparatus, a data converter, a forecasting unit, a state determination unit, and radar controller. The antenna apparatus radiates a radar pulse and receives a reflection pulse. The signal processing apparatus calculates a reception intensity, a Doppler speed, and a speed width. The data converter calculates rainfall intensity data and wind direction/speed data. The forecasting unit generates forecasting data based on the rainfall intensity data and on the wind direction/speed data. The state determination unit generates an observation sequence. The radar controller controls the antenna apparatus in accordance with the observation sequence.

1. A weather radar apparatus comprising:
an antenna apparatus configured to radiate a radar pulse and receive a reflection pulse of the radiated radar pulse reflected; a signal processing apparatus configured to calculate a reception intensity, a Doppler speed, and a speed width, based on the reflection pulse; a data converter configured to calculate rainfall intensity data based on the reception intensity, and calculate wind direction/speed data based on the Doppler speed and speed width; a forecasting unit configured to generate forecasting data which forecasts spatial distribution of a target rain, based on the rainfall intensity data and on the wind direction/speed data; a state determination unit configured to generate an observation sequence in a manner that, if the forecasting data includes data exceeding a setting value as a result of comparing the forecasting data with the setting value, an observation of an area corresponding to the data exceeding the setting value is performed in place of at least an observation of another area; and a radar controller configured to control the antenna apparatus in accordance with the observation sequence.
