SUMMARY
This chapter has presented information on radar maintenance procedures. The information that
follows summarizes the important points of this chapter.
Transmitter PERFORMANCE CHECKS are essential for you to maintain an efficient radar
system. The transmitter output must be monitored closely for both frequency and power.
Transmitter energy is distributed symmetrically over a band of frequencies known as the
SPECTRUM.
A SPECTRUM CURVE for a transmitter in good condition is shown in the illustration.
