中文摘要：

由于传统舰船检测方法较少考虑海洋表面微波散射机理、星载SAR舰船成像原理等影响舰船检测的因素,适应能力有限,该文对影响星载SAR舰船检测的关键因素进行了深入研究。通过对海洋因素、舰船因素、SAR系统因素等进行深入研究,详细说明了这些因素如何影响星载SAR舰船检测,并归纳总结了星载SAR舰船检测的发展趋势,为实现星载SAR舰船自适应检测奠定了基础。

英文摘要：

Conventional ship detection methods seldom consider factors influencing ship detection, such as the microwave scattering mechanism of the ocean surface and the spacehorne synthetic aperture radar （SAR） imaging principle of ships. These methods are tailored to specific image types,having limited adaptive ability. As a result,it is difficult to meet the increasing need of adaptive ship detection. This paper elaborates the key factors influencing ship detection. The key factors are categorized into ocean factors, ship factors and SAR system factors. By analyzing these factors in deep, this paper illustrates in detail how ship detection is influenced and the future development trend of ship detection in spaceborne SAR imagery.
