5.1 Components and Hardware
The radar sensor consists of an integrated microwave transmitter and sensor
together with a horn antenna (see FIGURE 5-2 and TABLE 5-1). The horn
antenna serves to focus the transmitted signal and to receive the reflected echo.
A built-in SDI-12 interface provides data processing and SDI-12
