In this chapter we will discuss some aspects of the choice of some main systems' parameters and their relations for multifunction operation. We consider the observation of the air space to detect, locate and track flying targets, the classical task of a surveillance radar. The aim is to establish a track for each target as early as possible. We have discussed in several chapters the arbitrary movement of the agile beam, which is generally a pencil beam. There is the desire to use this freedom in the most intelligent and effective way, which means to achieve reliable tracking of incoming targets with adequate location accuracy. The tracks should be established at a maximum range with a minimum of mean power. Thereafter, the tracks should be maintained with an adequate tracking rate and power.
