Effects of noise and system's parameters on the tomographic image reconstruction of ground surfaces

In a recent paper by the author (for original paper see ibid., vol. 48, p. 1384-1392 (2000)) it has been shown that using the measurements of the scattered fields produced by an isolated ground surface from transmitting antennas in different azimuthal directions, the distribution of the dielectric properties of the isolated ground surface can be reconstructed using well-established ground wave propagation theory. In practice, the operation of a system using this technique is subject to measurement errors and noise, and it also depends on a number of parameters including the operating frequency, the number of antennas used, and their locations. These effects are, thus, studied and the results of the reconstruction errors are presented.
