Operational and Siting Factors,his may be achieved by careful siting of the antenna. Another important item is energy reflection towards targets from a land or sea surface. As noted in section 2.2.3, this may substantially alter the antenna beam pattern. This chapter begins by describing some basic properties of clutter, and goes

Signal Processing and Display,nics and computer technology. The detailed hardware of modern radar signal processors varies widely between different installations. However, certain key principles are now well established and widely implemented. We shall concentrate on explaining these principles in this chapter.

Secondary Radar,transmitter and receiver. Like its primary counterpart, the signals from an SSR normally undergo plot extraction at the radar site, followed by transmission by landline to an ATC or operations centre. Secondary radar antennas are often mounted above primary antennas (see figure 1.2), saving the cost

Modern Surveillance Radar for Civil Air Traffic Control,no exception. Nevertheless, our account should give the reader an overall view of current equipment and trends. To save space and avoid repetition, we focus on somewhat different aspects of ATC radar in each country.

The Radar Equation,In this chapter we begin a more detailed account of radar. The first task is to develop a simple form of the .. This clarifies important relationships between such factors as transmitter power, receiver sensitivity, target size and range.
