简介：地震照明在表面下的成像起一个重要作用。一幅更好的图象也能通过优化获得几何学或介绍包含照明赔偿的更先进的地震移植或tomographic倒置方法被期望。垂直电报调查是为它的灵活性和数据质量的传统的海洋的地震调查的潜在的代替。处理的常规垂直电缆线数据在移植前要求primaries和multiples的分离。我们建议使用多尺度的完整的波形倒置(FWI)改进垂直电报调查的照明范围。一个深水速度模型被造在在海床下面检测低速度异例测试多尺度的FWI的能力。合成结果证明多尺度的FWI是在深海的探索的一个有效模型大楼工具。通过面向的照明分析和多尺度的FWI可以帮助减轻垂直电报调查的风险的目标的几何学优化。多尺度的FWI，低频率的数据和multi-vertical-cable获得系统的联合可以提供高分辨率和高保真度表面下的模型。
