Radar and Laser Cross Section Engineering

Since Radar and Laser Cross Section Engineering was first published in 1995 there have been dramatic changes in many aspects of radar cross section (RCS). The capabilities of commercial computer simulation tools, or more generally computational electromagnetics (CEM), continue to grow. Many sophisticated commercial software packages are available and they have been integrated into aerodynamic and mechanical simulation modules. The increase in computer memory and speed has made RCS simulations practical and accessible for realistic complex targets. Radar and Laser Cross Section Engineering, Third Edition reflects recent developments that have found applications in both the military and civilian sectors. These developments have been fueled by the growth in computer technology, signal processing techniques, and new materials that have interesting and unusual electric and magnetic behavior. Many concepts conceived decades ago have finally become a reality. In particular, capabilities of modem radar to process and track many targets in hostile battlefield conditions and severe clutter have continued to improve. In addition to radar, many other types of sensors are used to detect, track, and identify targets. Radars have found application in self-driving cars, robotics, and medical diagnosis. In all these systems the target's RCS must be quantified and incorporated into the system design and operation. Commercial applications have helped to drive down the size, weight, and cost of radar sensor systems. The development of composite and artificial materials continues as well. Artificial metamaterials is an increasingly active area of research. In addition to new discussions in the developing areas already mentioned, more homework problems and examples have been added to this new edition. The presentation of the material assumes that the student has mastered electromagnetics at an undergraduate level. Completion of a course inantennas also is a helpful prerequisite to this book, although students without an antenna background have successfully mastered the material presented here.
