The paper describes a new adaptive canceller for estimating the elevation angle in a low-angle tracking radar environment in the presence of specular and diffuse multipath. The adaptation is achieved using the complex least-mean-squares (LMS) algorithm. Computer-simulation results are included to demonstrate the usefulness of this scheme for estimating the elevation angle when it is a small fraction of a standard beamwidth.

“…A treatment of diffuse scattering contributions to multipath has recently been provided my McGarty [11] which is somewhat more detailed than the present approach in which the emphasis is on a technique for handling specular scatter contributions using the half-plane results discussed above. The present treatment of diffuse scatter employs the scattering coefficients available in the literature (see Barton [12] or Beckmann and Spizzichino [13], for example).…”

“…In specifying the grading criteria, the expressions developed allow for the treatment of several statistically different surfaces with the requirement that the solutions be selfconsistent when the roughness of each adjacent surface is equal. IEEE 11. Diffuse Contribution to the Scattered Fields and DDM In general, diffuse contributions to scattered fields are not easily obtained from theoretical considerations.…”

A technique for calculating the derogation in the difference in depth of modulation (DDM) signal, used for aircraft glide slope guidance, due to slightly rough ground surfaces is developed. The contributions to the scattered signal from diffuse and specular scatter are treated separately. The diffuse derogation is calculated based on empirical data, and an average variation is presented. The specular contributions to the variation in the signal is calculated based on expanding the half-plane diffraction solution in terms of the ground roughness. A specular scattered deviation about the mean signal is then obtained by statistically averaging over normally distributed ground heights. Results of the analysis indicate that substantial relaxation in grading criteria can be effected.
