摘要

本文利用因加拉雷达在29°~ 38°掠掠角范围内采集的数据，对雷达海杂波的多普勒频谱进行了表征。结果表明，最近提出的较低掠掠角的建模和仿真方法仍然适用于该数据。建模方法也被扩展到捕捉观察到的双峰行为，从破碎波向上或向下风向的高强度回报。

Characterising the Doppler spectra of high grazing angle sea clutter

This paper characterises the Doppler spectra of radar sea clutter using data collected by the Ingara radar at grazing angles in the range 29° to 38°. It is shown that recently proposed modelling and simulation methods for lower grazing angles are still applicable for this data. The modelling method is also extended to capture the bimodal behaviour observed with high intensity returns from breaking waves looking up or downwind.
