This is the first book to focus specifically on antenna RCS reduction theory and design approaches. It covers both principles and engineering practice, and provides an in-depth study of a number of important topics, including fundamental theory, antenna and array analysis models, the rapid numerical computation method, and various low-RCS antenna design methods. The comprehensive and systematic discussion of practical issues in antenna RCS reduction makes it an ideal resource for readers interested in practical solutions to antenna stealth, particularly researchers, engineers and graduate students in the fields of microwave engineering, electrical and electronic engineering, and telecommunications engineering.
Electronic warfare (EW)—also known as electronic countermeasures (EMCs)—is a type of warfare based on modern technology involving electronic reconnaissance, counter-reconnaissance, electronic jamming, anti-interference, electronic stealth, and anti-stealth techniques. Stealth technology plays an important role in modern EW. In view of its major impact on warfare, stealth technology will be increasingly used in future high-tech EW applications. Consequently, more countries around the world are developing it.
Radar cross section (RCS) reduction is a method of controlling and reducing the radar characteristics of military targets, which reduces the combat effectiveness of enemy electronic detection systems and weapon platforms, thus enhancing the penetration and survival capabilities of military equipment. In a narrow sense, RCS reduction (RCSR) can be considered to be antiradar stealth technology. Moreover, the stealth technology aimed at improving RCSR comprises four basic methods—that is, stealth design shape, radar-absorbing materials (RAMs), passive cancellation, and active cancellation methods, the first two methods being the most commonly used. Changing the design shape and using RAMs can reduce the RCS of military platforms. However, for low observable technology, the antenna can contribute much of the total RCS. Consequently, consideration of the antenna RCS has become increasingly important.
Antennas are one of the major contributors to the total RCS of the equipment on an aircraft, so technicians must take steps to reduce the antenna RCS. Moreover, the radar antenna system—comprising a radome, radar antennas, and a radar module—usually produces a strong RCS in the nose cone of an aircraft. Using a typical tactical missile as an example, the RCS of its terminal guidance radar—that is, the Cassegrain antenna—can be as high as 10 dBsm under horizontally polarized incident waves in the X-band. Similarly, the RCS of a planar slotted array antenna used in Doppler radar can reach up to 30 dBsm. Consequently, the RCSR of antenna systems is a key technology in target stealth applications. However, owing to the limitations of the antenna system’s working characteristics, RCSR must ensure the normal reception and transmission of electromagnetic (EM) waves. Thus, conventional stealth methods—such as shape stealth technology and RAMs—cannot be simply applied to antenna RCSR, making the stealth of antenna systems a key problem in stealth technology applications for military aircraft. Currently, there is no ideal way to substantially reduce the antenna RCS without influencing the radiation performance of the radar antenna. Consequently, trade-offs between these factors have to be made in practical engineering applications.
