Abstract. This article presents the basic theoretical background of a method for measu­ring reflective surface height using reflected signals from global navigation satellite systems, known as GNSS reflectometry. It also presents the results of reflective surface height mea­­su­rements from the metrobridge in Nizhny Novgorod using this method. The mea­sure­ments were conducted over three days, from September 22 to 24, 2025. Based on these measure­ments, reflective surface height estimates were obtained. Method provides sufficiently accu­rate reflective surface height measurements and, in the future, a device operating on the basis of this method can be used as a tide gauge.

Keywords: bistatic radar, global navigation satellite systems, GNSS reflectometry, ref­lective surface height
