Introduction,ars passed before systematic experiments in radio detection began. Early work used continuous-wave (CW) transmissions, and relied upon interference between a transmitted wave and the doppler-shifted signal received from a moving target. The detection of aircraft was first accomplished in the USA in 1930.

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
