Abstract

In the first section of this chapter we deal with the nature of the received signal, the need for averaging signals, application of various corrections and display of reflectivity. This is followed in section 3.2 with the digital processing of reflectivity and parameters derived from it. Section 3.3 deals with methods of processing of Doppler parameters viz. mean velocity and spectrum width and resolution of ambiguities. The use of multiple-Doppler, dual-Doppler and single Doppler radars and characteristic signatures of wind patterns are also discussed in this section. In section 3.4 we discuss methods of recognition and suppression of ground clutter and anomalous propagation echoes. Section 3.5 deals with techniques used on airborne weather radar. In section 3.6 we describe some modern ground-based operational Doppler radars. Section 3.7 deals with the implementation of polarimetric capability and describes some polarimetric radars.
