Abstract
The radar cross section (RCS) of an object represents its electromagnetic scattering properties for a given incident wave. The analysis of scattered field is critical in military and defence arenas, especially while designing low observable platforms. It is seen that the presence of an antenna/ array on the target influences its echo area significantly. The primary cause for such scattering of the incident signals is the reflections that occur within the antenna aperture and its feed network. This book presents detailed analytical formulation for the RCS of parallel-fed linear dipole array in the presence of mutual coupling. The RCS estimation is done based on the signal path within the antenna system. The scattered field is expressed in terms of array design parameters including the reflection and transmission coefficients. The computed results presented show the variation in the RCS pattern for cases of with and without mutual coupling. The effect of finite dipole-length, inter-element spacing, scan angle, array configuration, amplitude distribution and terminating load impedance on the RCS pattern is studied. It is shown that the array RCS can be controlled by choosing optimum design parameters, including terminating impedance and geometric configuration. This book explains each step of the RCS estimation and analysis of dipole array with detailed schematics, tables and illustrations. Moreover it includes parametric analysis of RCS estimation and control. This book helps reader to understand the physics of the scattering within the phased array system.
