<p><P>PROBLEM TO BE SOLVED: To obtain a reflection structure achieving low RCS (Radar Cross Section). <P>SOLUTION: The reflection structure includes an approximately board-like ground conductor 100, and a plurality of metal small plates 101 arranged over the ground conductor 100 approximately in parallel with the surface of the ground conductor 100. Since the size of each metal small plate 101 is determined by using a code 103 of a prescribed bit cut out from a pseudo noise code series 102 (or a multi-value pseudo noise code series), when a plane electromagnetic wave enters the reflection structure, a wavefront of a reflected wave is not planar and consequently, RCS is reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
