Low observable (LO) aircraft and cruise missiles give U.S. military forces the technical capability to attack ground targets with less risk of engaging enemy defenses. But full use requires an intelligence infrastructure that can support their special capabilities. This monograph suggests the need for dialogue among the intelligence and mission planning communities, the aircraft developers, and the aircraft operators addressing issues in nine areas: 1) threat data requirements to support LO platform development, testing and employment; 2) types of threat data currently available and additional types needed; 3) constraints on data security and access; 4) validation of threat models used in penetration analysis; 5) interface of unit-level intelligence support workstations with mission-planning systems; 6) route-planning that considers mobile threats, airborne interceptors, and anti- aircraft artillery; 7) operational alternatives to enhance LO penetration capabilities; 8) automated procedures for route planning; 9) route-planning capabilities onboard LO aircraft.

This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.
