Chapter: Radar Transmitter
A radar transmitter generates RF- energy necessary for scanning the free space. The often very large amount of energy must be modulated by a pulse from the synchronizer in a specific time pattern to obtain a time reference for time measurement of the signal.
Learning Objectives
This chapter describes the different types of transmitters used in radar sets. Upon completion of this chapter you will be able to:
- Describe the general task of and know the demands on a radar transmitter,
- State the meaning of the term „Coherence”
- Describe the general design of a fully-coherent radar transmitter and compare it with
- the general design of a pseudo-coherent radar transmitter.
- Describe the general construction and physical appearance of the velocity modulated vacuum tubes magnetrons, klystrons and traveling wave tubes.
