These principles can basically be implemented in a radar system, and allow the determination of theĭistance, the direction and the height of the reflecting object.įigure 1: “Würzburg Riese”, World War II radar Reflected waves are received again at the place of their origin, then that means an obstacle The electromagnetic waves are reflected if they meet an electrically leading surface. Electromagnetic energy travels through air at approximately the speed of light, (The effects atmosphere and weather have on this energy will be discussed later however, for thisĭiscussion on determining range, these effects will be temporarily ignored.) Will vary only slightly because of atmospheric and weather conditions. This energy normally travels through space in a straight line, at a constant speed, and Radar measurement of range, or distance, is made possible because of the properties of radiated Some laws of nature have a greater importance here. Systems involve a wide range of disciplines such as building works, heavy mechanical and electricalĮngineering, high power microwave engineering, and advanced high speed signal and data The implementation and operation of primary radars An understanding of the theory is essential in order to be able to specify and The basic principle of operation of primary radar is simple to understand. Interrelationships of the basic units of a radar system. using a block diagram, describe the basic function, principles of operation, and
know the advantages of a frequency diversity radar describe the factors that contribute to or deteriorate from radar resolution discuss how pulse width, peak power, and beam width affect radar performance define range, bearing, and altitude as they relate to a radar system explain the basic operation of a pulse radar system Key performance parameters associated with primary radar specifications. At the end of this chapter, students should understand the fundamentals of radar and recognize the It is intended to give aīackground in radar theory, including radar principles, propagation, radar signals, resolution and the radarĮquation. This chapter provides theīasis for understanding the subsequent chapter on the specific sub system modules. This firstĬhapter of the Radartutorial deals with mathematically basics of Radar Technology. The learning objectives are a preview of the information you are expected to learn in this chapter.
