摘要

相干垂直阵列(CoVA)系统被设计用于沿海陆海空相互作用(CLASI)任务中，通过测量入射导管信号的掠射角来估计蒸发导管高度(EDH)。在CoVA系统中，由于导管信号的掠角较窄，微小的变化会导致EDH估计的大变化，因此需要高的角分辨率和相位相干性。本文讨论了CoVA系统的设计和实现高相位相干性的方法。CoVA在CLASI期间获得的结果将在以后的工作中介绍。

A Fully Coherent Array for Evaporation Duct Height Estimation at Coastal Boundaries

The Coherent Vertical Array (CoVA) system has been designed to be used during the Coastal Land-Air-Sea Interactions (CLASI) mission for evaporation duct height (EDH) estimation by measuring the grazing angle of the incident, ducted signal. High angular resolution and phase coherence is needed in the CoVA system due to the ducted signal having a narrow grazing angle with small variations translating to large variations in EDH estimation. This paper discusses the design of the CoVA system and the methodology used to achieve high phase coherence. The results obtained by CoVA during CLASI will be presented in future work.
