Refractivity‐from‐clutter (RFC) is a technique for remote sensing of the lowest portion of vertical atmospheric refractivity profile, particularly evaporation and surface‐based ducts. It uses the sea‐surface backscattered radar signal to estimate the ducting conditions. The Lower Atmospheric Propagation (LATPROP) radar is a software‐defined, coherent‐on‐receive remote sensing system built on a low‐cost, commercial off‐the‐shelf marine radar platform operating at 9.41 GHz. The system is designed to specifically operate as a RFC‐capable platform sensitive to low clutter power returns from the sea surface. This paper examines the appropriate radar design, system modifications, and radar signal processing steps, and provides a comparison with existing RFC‐capable systems. The LATPROP system was deployed during the Coupled Air‐Sea Processes and electromagnetic Ducting Research West Campaign that took place off of the coast of Southern California during October 2017 and was shown to accurately capture the effects of the ducting conditions.

能够从杂波中读取的,软件定义的,相干接收海洋雷达

杂波折射率(RFC)是一种用于遥感垂直大气折射率分布的最低部分的技术,尤其是蒸发和基于地面的管道。它使用海面后向散射雷达信号估计管道状况。较低大气传播(LATPROP)雷达是一种软件定义的,相干接收的遥感系统,它建立在运行于9.41 GHz的低成本,商用现货船用雷达平台上。该系统经过专门设计,可作为具有RFC功能的平台运行,对从海面返回的低杂波功率敏感。本文研究了适当的雷达设计,系统修改和雷达信号处理步骤,并与现有的具有RFC功能的系统进行了比较。
