This chapter introduces some of the major radar concepts that will be described in greater detail in subsequent chapters. One key concept, however, is covered primarily in this chapter: the radar range equation (RRE). Although specific forms of the RRE are discussed in other chapters, its derivation and definitions of all major terms are covered here. The remainder of the chapter provides an overview of other significant radar concepts.
