Statistics Properties of Real High Resolution Sea Clutter Data Amplitude at Large Grazing Angles
摘要
Abstract
The Ku-band, high-resolution sea clutter data at high grazing angles was used to fit the common theoretical models, including rayleigh distribution, Weibull distribution, logarithmic normal distribution, K distribution and KK distri?bution. The fitting effect of these distribution methods was analyzed in this paper and the results showed that the amplitude of sea clutter was close to rayleigh distribution in the case of large grazing angle and tail of the amplitude distribution curve of the sea clutter in some distance units deviates from the rayleigh distribution while the K and KK distributions couldfit better.关键词
