This paper deals with scattering characteristics of anomalous bodies withvaried shapes and parameters under the excitation of the field of half-wave-length dipole antenna in the homogeneous lossy media. The integral equationfor magnetic field from the scattering of highly-conducting spheroid and theintegral equation for electric field from rectangular anomalous body with limi-ted conductivity are respetively calculated by moments method; some prob-lems related to numerical method such as approximation,error and test are dis-cussed; the regularities of variation in scattering field with the change in suchfactors as electric parameters of media and the size, shape and spatial positionof the scattering body are obtained through the numerical calculation. Themeasurement results of scattering from metallic spheroid and media mass underthe water are fairly consistent with the numerical calculations, suggesting thecorrectness of the numerical model.
