Finding ways to interfere with or jam communication signals is an essential area of electronic warfare (EW). In modern EW systems, anti-jam technology has been employed to overcome signal jamming. Recently, electronic warfare R & D has focused on creating methods to disrupt these anti-jam systems. This newly revised and greatly expanded edition of the popular Artech House book, Modern Communications Jamming Principles and Techniques, provides an up-to-date, exhaustive treatment of the techniques and methods available to create countermeasures against anti-jam, over-the-air communications. The Second Edition features a wealth of new material on urban warfare, including a computer simulation of EW architecture alternatives for land-based forces based on urban constraints. This unique resource is dedicated to showing professionals how to design and build jammers specifically targeted at anti-jam communications. Moreover, practitioners find assistance in evaluating the expected performance of jamming systems against modern communications systems.
