Azimuth beamwidth effect on radar sensed terrain horizon profiles
Abstract
A method is presented for smoothed horizon generation. The mathematical model used computes elevation angle measurements for a phase-monopulse radar by considering a number of individual scattering points within the antenna beamwidth at the horizon range. Simplification of the mathematical model permits rapid generation and thus reasonable computer costs. Example smoothed horizons are shown and errors due to mathematical model simplification are analyzed. The smoothed horizon generation method is applied to the simulation analysis of a horizon checkpointing system. Results indicate that good position identification can be achieved with relatively wide azimuth beamwidths.
