摘要

利用海面后向散射可以反演海洋和沿海地区的低层大气导管。这种技术被称为杂波折射率(RFC)。改进目前可用的RFC技术是一个活跃的研究领域。管道对电磁信号的影响取决于信号发射的角度。因此，使用多个发射角度可能是改进RFC反演技术的好方法。本文从理论上研究了在RFC反演中使用多个发射角相对于使用单一发射角如何提高风道估计。

A Comparison Between Multiple Launch Angle Method (MLAM) and Single Launch Angle Refractivity-from-Clutter (RFC) Technique

Lower atmospheric ducts in ocean and littoral regions can be retrieved using sea surface backscattering. This technique is called Refractivity-from-Clutter (RFC). Improving currently available RFC techniques is an active area of research. The duct effects on an EM signal depends on the angle that the signal is launched. Hence, using multiple launch angles might be a good way to improve the RFC inversion technique. This paper is a theoretical study of how using multiple launch angles in RFC inversion can improve the duct estimation with respect to using a single launch angle.
