Learning Objectives
The learning objectives is a preview of the information you are expected to learn in this chapter. This first chapter of the Radartutorial deals with mathematically basics of Radar Technology. This chapter provides the basis for understanding the subsequent chapter on the specific sub system modules. It is intended to give a background in radar theory, including radar principles, propagation, radar signals, resolution and the radar equation. At the end of this chapter, students should understand the fundamentals of radar and recognize the key performance parameters associated with primary radar specifications.
This chapter gives an overview of mathematical and physical basics.
The student should be able to:
- explain the basic operation of radar systems;
- define range, bearing, and altitude as they relate to a radar system;
- discuss how pulse width, peak power, and beam width affect radar performance;
- describe the factors that contribute to or deteriorate from radar accuracy;
- know the advantages of a frequency diversity radar;
- using a block diagram, describe the basic function, principles of operation, and interrelationships of the basic units of a radar system.
