Introduction to Radar

Abstract

The word radar was a code name used by the U.S. Navy in 1940, early in World War II, and is an acronym derived from the phrase radio detection and ranging. Radar has many uses, and a particular application can involve extremely complex and sophisticated engineering techniques and designs; however, radar is very simple in its most basic form, as shown in Figure 1-1. Its basic objectives are to detect targets of interest and to derive information such as range, angular coordinates, velocity, and reflectivity signature from the detection.
