ABSTRACT
In Chapter 4, the theoretical basis was given for transmission of sound in directed beams and receiving echo signals. The basis for interpreting these signals in terms of turbulent parameters and wind speed components was discussed in detail. In particular, it is evident that acoustic beam patterns are seldom simple and that interpretation of echo signals requires knowledge of the remote-sensing instrument design. In this chapter we discuss the details of actual designs, so the connection can be made between hardware elements in Chapter 5 and the theoretical considerations of Chapter 4.
