| description | This article investigates the strategies to measure the scattering matrix and the extinction coefficient of the chaff corridor. A complete error model is adopted to describe the power transmission properties of the indoor measurement system. Based on this model, a polaristic calibration method is employed to correct the measurement errors. After calibration, a scattering matrix measurement method for different types of chaff corridors is addressed. When dealing with the extinction coefficient measurements, Beer-Lambert's law is introduced to describe the power loss of the electromagnetic wave passing through the chaff corridor. According to this law, a method of the extinction coefficient measurement for the chaff corridor is proposed. Finally, simulations and measurements are conducted to verify the methods presented in this article and obtain the electromagnetic scattering properties of various types of chaff corridors. Experimental results show that the scattering matrix and extinction coefficient are not sensitive to the polarization of the incident wave for uniformly distributed chaff corridor. Besides, high attenuation occurs when electromagnetic wave passes through the chaff corridor. |
