Clutter suppression device and radar device including the same

摘要

A clutter suppressing device (20) for suppressing echo data of static clutter components indicating reflection waves caused by radar transmission signals reflecting on a static object is provided. The device (20) includes a static clutter component suppressor (21) configured to receive reception signals containing the static clutter components, and suppress the static clutter components, a reference data memory (23) configured to store, as reference data, echo data of the reception signals obtained in fine weather and in which the static clutter components are suppressed by the static clutter component suppressor (21), and a rain component extracting module (24) configured to extract echo data indicating rain components contained in the reception signals, by removing the reference data stored in the reference data memory (23) from echo data of the reception signals obtained in rainy weather and in which the static clutter components are suppressed by the static clutter component suppressor (21).
