Radar One-Dimensional Range Profile Dynamic Jamming Based on Programmable Metasurface

Abstract

In this letter, a wideband programmable metasurface, which consists of 20 × 20 1 b reflection unit cells, is designed and fabricated to perform radar one-dimensional range profile (ODRP) dynamic jamming. The quasi-butterfly reflection element soldering p-i-n diode is proposed to realize reflection phase difference of 170° ± 10° between the <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</small> and <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">off</small> states over the whole <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">X</i> -band. The unified control of the whole column diodes is developed to simplify the code control feeding network on the same layer for easy process. The radar ODRP is tested and it is verified that the ODRP of the proposed metasurface is dynamically adjustable in the range of 20 dB in real time over the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">X</i> -band, fully proving the great potential application in the radar jamming, deception, and anti-identification.
