Analysis of Reflection Coefficients Impact on Multipath Error

The environment and structure of the reflecting surface plays major role in estimating the relative amplitude of the multipath signals. Multipath is separated into two major classes based on the type of reflecting surface [1]: specular and diffuse. The specular reflection properties are important for understanding the multipath propagation of the Right Hand Circularly Polarized (RHCP) GPS L1 signal. Hence, in this paper, the characteristics of specular multipath in terms of reflection coefficients is analyzed by taking into account some of the specularly reflective surfaces.
