Assessment Method of Multipath Mitigation Performance for GNSS Antenna with Receiver Algorithms

Figure 1

This figure shows how multipath signal is produced. Multipath signals are mainly produced by two kinds of reflective surfaces: horizontal surfaces and inclined surfaces. Elevation angles of multipath signals caused by horizontal surfaces equal to negative elevation angles of direct signals. Elevation angles of multipath signals caused by inclined surfaces depend on both the elevation angles of direct signals and the dip angles of the surfaces.
