Abstract :
Spatial averaging is used in conjunction with the normalized data to remove errors in acquiring transmission coefficients from finite material panels. This is illustrated by data obtained from a UTD code, NEC-BSC, and a MM code, ESP. The errors from the scattering from the edges of the panel and scattering between the receiving antenna and the panel are effectively removed with this technique. The minimum size of the panel needed as well as the necessary starting, ending and number of samples points will be discussed.
