METHOD OF DETECTING AND COMPENSATING FOR PRECIPITATION IN SODAR SYSTEMS |
摘要 |
A method of detecting precipitation with a sodar apparatus (200) that transmits sound beams (31) into the atmosphere, detects echoes returned from the atmosphere, from the echoes determines a Doppler-shifted spectrum (41, 42) comprising the relative strength of the echoes at various Doppler-shifted frequencies, and estimates wind speed and direction. The method includes automatically estimating the presence of precipitation (42) based on the Doppler-shifted spectrum (41, 42). |
