摘要

雷达SAIL (Aguttes et al.， and Aguttes)是CNES发明的一种SAR卫星概念，基于放置在轨道平面上的短(<5 m，沿速度矢量)垂直天线。这种令人惊讶的垂直几何形状已被证明适用于雷达，同时使一系列其他创新融合到整个卫星的全新设计中，以实现简化和降低成本的最终目标。本文着重于天线几何形状，揭示了新的优势，这些优势概括了利用范围，加强了SAIL概念的优点，但也证明了在标准总线上实施这种天线的合理性，至少对于中等天线尺寸。

The radar SAIL and other short vertical antenna space SAR concepts

Radar SAIL (Aguttes et al., and Aguttes) is a SAR satellite concept invented by CNES, based on a short (<5 m, along speed vector) vertical antenna placed in the orbit plane. This surprising vertical geometry has been proven to work properly for radar while enabling a cascade of other innovations converging into a radically new design of the whole satellite for an ultimate goal of simplification and cost reduction. This paper focuses on the antenna geometry and unveils new advantages which generalise the utilisation range and reinforce the merits of the SAIL concept but also justify the implementation of such antenna on a standard bus, at least for moderate antenna size.
