Use of wavelets decomposition to reduce outside transmissions during measurement of RCS

Abstract

If the RCS of a target is measured in measurement facility which is not a Faraday cage, this RCS might be corrupted by eventual outside transmissions which fill the same spectral band than measurement. In this situation, outside radiations are going to pollute the value of the measured RCS and as a consequence their level must be reduced in order to be able to get correct values of RCS. This article deals with a mathematical method which allows limiting the influence of interferences on the measured values of RCS thanks to the use of wavelets.
