Synopsis

The purpose of the package is to answer the question 'What is the radio field strength at a certain point?' when power is radiated from a transmit­ ting source. Because of the complexity of the question in general, it can only be answered at present in certain idealized situations. Nevertheless it is valuable to have quantitative data available for these situations. The package is divided into two parts. In the first of these, propagation in free space and over a flat earth are dealt with. In the second, propagation over a spherical earth is considered. In the free-space situation the power density of the signal in a given direction will fall as the inverse square of the distance from the source. For propagation from a transmitting source at an arbitrary height above a perfecdy conducting flat earth, the field strength at large distances can be 3 dB higher than in free space. With a finite conduc­ tivity earth, the field strength will be lower than this because of the power dissipation in the earth.

About this title

Synopsis

This software package aims to enable engineers and researchers concerned with radiowave propagation studies and applications in communications, broadcasting, radar and remote sensing to quantify radio field strengths over ground. The ground may be homogeneous or inhomogeneous, smooth or irregular in height, and the model of the earth used may be planar or spherical. The authors use an original technique for solving the complex mathematics involved, demonstrated in a related book, "Radiowave Propagation Over Ground", also published by Chapman and Hall. This book should be of interest to engineers, scientists and graduate students in microwave and R F for telecoms, radar and remote sensing.
