Detectability of low flying targets in real terrain using a diffraction model
Abstract
A method for the evaluation of transhorizon radar ranges in a short distance environment is described. The method is based on detailed terrain structure information using a digital terrain data base and on a multiple knife edge diffraction propagation model. From the results of a number of simulations in the different types of terrain being typical for Central Europe, mean transhorizon radar range curves are obtained, indicating the capability of radar systems to detect targets beyond the horizon. Varying parameters are the radar wavelength, the radar antenna height and the maximum free space radar range, where the latter depends on radiated power, antenna gain, radar cross section, and other parameters.
