Low Altitude Radar Wave Propagation Modelling: All Algorithms and Verification with Other Propagation Model and Measurement Data of Low Altitude Radar Wave Propagation Modelling
Orhan Sengul
A robust technique for the prediction of field strengths over irregular terrain profiles must be polarization and frequency dependent, and must take electrical properties, and details of the terrain profile into account. An efficient method (RADCAL) has been presented to model groundwave propagation over irregular terrain in the presence of range-dependent nonstandard environmental conditions. The results from this model were compared against measured data and other existing models and were shown to give predominantly excellent agreement. The final objective in model development is to produce a real-time capability for predicting signal levels for operational assessment, whether it be for military or civilian requirements. We have presented a ray optics based method to estimate the path propagation factor of an irregular terrain. Explicit expressions are obtained for the Divergence and Convergence factors for the convex and concave spherically shaped slant plateaus joining the hills and depression. The algorithm developed is very fast and provides good estimates of the propagation factor. Numerical predictions are compared with other full wave and GO methods and also measurements.
