State the operational principles of tr and atr tubes. Describe the basic operating sequence of series and parallel connected duplexers. List the basic design requirements of an effective radar receiver. List the major sections of a typical radar receiver. Using a block diagram, describe the operational characteristics of a typical radar receiver.
Any radar system has several major subsystems that perform standard functions.
These major subsystems were briefly described in chapter 1. This chapter will describe the operation of the synchronizer, transmitter, duplexer, and receiver of a typical pulse radar system and briefly analyze the circuits used. Chapter 3 will describe typical indicator and antenna subsystems. Because radar systems vary widely in specific design, only a general description of representative circuits is presented in this chapter. We will use the term synchronizer in our discussion.
