In this chapter, the information contained in a radar pulse will be presented first. Then some of the difficulties encountered in receiver research will be stated. A very simple discussion on analog and digital receivers will then be presented and, finally, the characteristics of EW receivers will be discussed. If several definitions of one term are available, only the ones that have a direct impact on EW receivers will be discussed. All the characteristics presented here are measurable quantities and the measurements will be presented in Chapter 14. Finally, the research trend in EW receivers will be discussed. Readers with EW background can skip this chapter.
