Abstract

Abstract

To reduce Radar Cross-Section (RCS), improve operation bandwidth, this paper proposes an innovative Salisbury screen based on time-controlled surface and researches the frequency shifting of UHF radar signal. First, a reflective modulation board which is composed of adjustable impedance sheet, dielectric spacer and grounded slab is presented by using the controllability of electromagnetic properties. Second, the equivalent circuit of dynamic two-phase transmission line is established, and an inductance layer is loaded on a periodic Frequency Selective Surface (FSS). Theoretical derivation and simulation results show that Salisbury screen can realize the spectrum shifting for UHF radar signal with large bandwidth, multi-directional, as well as different polarizations. Moreover, this screen can reduce RCS and detection probability of the long distance moving target.
