초록

In military weapon systems, the cockpit canopy that occupies a large region of a fighter aircraft requires both high visible light transmittance and Radar Cross Section(RCS) reduction performance. In this investigation, the monostatic RCS of an acrylic dielectric coated with a transparent conducting oxide that can realize high light transmittance and low haze characteristics in the visible spectrum, was experimentally analyzed. To calibrate the RCS measurement, assuming a perfect electric conductor, a conducting plate made of copper was used and the measurement error was minimized by satisfying the far-field condition of the antenna and scatterers. The monostatic RCS of TCO single-sided and double-sided coated samples was measured. As a result, an RCS reduction of approximately 2.9 dB and 7.24 dB, respectively, was confirmed under normal incidence condition, compared to the conducting plate. In addition, RCS variations of each sample were confirmed by measurement performed at 5° and 10° oblique incidence.
