An important aspect of Electronic Warfare is the development of Radar Warning Receivers (RWR). Radar Warning Receiver/Electronic Warfare Receiver provides superiorperformance to protect tactical, transport and special mission aircraft in today’s modern electronic combat environment. Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their purpose is to issue a warning when a radar detects a threat. The warning can then be used, to find out the detected threat.The performance and design aspects of radar receivers will be considered in this project. For this purpose, the radar receiver will be defined as that assemblage of components within the radar system which is required to detect, amplify, and present the desired information as gathered at the radar location. This project is focused mainly on electronic warfare radar systems and describes the receiver front end design, as well as thesoftware algorithms used to determine signal characteristics.
