| 摘 要： | 用KZS算法(地物回波)做标准来实现X波段气象雷达回波的微波衰减订正.首先对晴空地物回波进行多次采样,表明地物回波强度具有较好的稳定性.然后对业务性X波段气象雷达回波强度衰减订正进行观测,同时把订正后的回波与采用经验公式进行衰减订正的雷达回波强度进行比较,结果表明地物回波衰减订正法对X波段气象雷达衰减订正是可行的.

| Abstract: | With the KZS algorithm the wavelet attenuation correction of the X-band weather radar is realized by using the ground-clutter echo as the criterion. The collection of the ground-clutter echo in the dry-weather period shows the stability of this echo during the considered period. The observation of the attenuation correction of the operating X- band weather radar echo intension is compared with the echo intension after the correction and the echo intension is corrected by the empirical formula. The result shows the feasibility of the ground-clutter echo for the correction of the ground-based X-band weather radar data. |
