Beschreibung
Zusammenfassung:	The present invention provides an acoustic resonance type precipitation gauge, comprising: a spherical body having an inner space; a receiver located in the inner space, and receiving sound waves formed in the inner space when at least one of rain, snow, and hail, generated by weather phenomena, collides with an outer surface of the body; an analysis unit for analyzing a component value in a certain frequency component of frequency components included in the received sound waves by performing signal processing for the received sound waves received from the receiver; and a calculation unit calculating the amount of precipitation in accordance with the component value in the certain frequency component analyzed by the analysis unit. 본 발명은 내부공간을 가지는 구 형상의 본체; 상기 내부공간에 위치하여 기상현상에 의해 발생하는 비, 눈, 우박 중 적어도 어느 하나가 상기 본체의 외표면에 부딪칠 경우에 상기 내부공간에 형성된 음파를 수신하는 수신기; 상기 수신기로부터 수신된 수신음파를 신호 처리하여 상기 수신음파 내 포함된 주파수 성분 중 특정주파수 성분에서의 성분값을 분석하는 분석부; 및 상기 분석부에서 분석된 상기 특정주파수 성분에서의 성분값에 따른 강수량을 산정하는 산정부; 를 포함하는 음향 공진형 강수량계를 제공한다.
