本文对S波段单基地和双基地海杂波数据的幅度谱和多普勒谱统计特性进行了比较分析。这些数据涵盖了从60°到120°的一系列双基地角度，包括同时进行的单基地、共极化和交叉极化双基地记录，提供了它们统计特性的直接比较。振幅数据的时间序列拟合的复合K和K +噪声分布在距离域和多普勒域中，和形状参数的变化被提出为单基地和共极化和交叉极化的双基地数据作为指示的尖峰的杂波。从这个参数的分析，它表明，交叉极化的双基地数据往往是不太尖的距离和多普勒域比同时共极化的双基地数据，比同时单基地数据，这可能是有利的雷达检测性能，特别是对于低能见度的海上目标。
This study presents a comparative analysis of amplitude and Doppler spectra statistics from monostatic and bistatic sea clutter data at S-band. These data cover a range of bistatic angles from 60° to 120° and include simultaneous monostatic and co-polarised and cross-polarised bistatic recordings, providing direct comparison of their statistical properties. The time series of amplitude data are fitted to the compound K and K + noise distribution in the range domain and in the Doppler domain, and the variation of the shape parameter is presented for monostatic and co-polarised and cross-polarised bistatic data as an indication of the spikiness of the clutter. From the analysis of this parameter, it is shown that cross-polarised bistatic data tend to be less spiky in the range and Doppler domain than the simultaneous co-polarised bistatic data, and than the simultaneous monostatic data, which could be advantageous in terms of radar detection performance, especially for low-visibility maritime targets.
