Abstract

The results of measurements of the angular dependences of radar backscatter coefficient and radio brightness temperature are presented. The measurements were carried out using a nanosecond radar with a carrier frequency of 9.95 GHz and a radiometer with a central frequency of 11.2 GHz installed on an automobile tower 16 m high. The test site is a potato field representing a regular structure in the form of parallel combs. The polarization features of the radar backscatter coefficient are determined. The experimental angular dependences are compared with the known models. The best accordance is marked with exponential models. Comparison of the angular dependences of the radio brightness temperature and the reflection coefficient shows their coincidence in the angular range of 40-90 degrees.
