Good transmittance of airborne radome is an important factor to ensure the efficient operation of antenna system. The transmittance is not only affected by the condition of radome itself, but also by the direction, frequency and polarization of electromagnetic wave. In order to solve the problems complex construction ,difficult realization and large test error of radome transmittance test system,etc.A radome transmittance test system is constructed ,and the radome transmittance under different incident angles electromagnetic wave frequencies is tested. The measured results of planar helical radome show that different incident angles in low frequency band have less influence on the transmittance of radome, while large incident angles in high frequency band have greater influence on the transmittance.
