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.

在测量RCS时,使用小波分解来减少外部传输
如果在非法拉第笼的测量设备中测量目标的RCS,则该RCS可能会被最终填满与测量相同频谱带的外部传输所破坏。在这种情况下,外部辐射会污染测量的RCS值,因此必须降低它们的水平,以便能够得到正确的RCS值。本文讨论了一种利用小波来限制干扰对RCS测量值影响的数学方法。
