The back side of the reflector is optionally equipped with a heater coil. It is
covered and sealed with a molded lid which provides also extra stability for the
reflector. The energy consumption increases with decreasing temperatures
and amounts to maximum 500 W. The heating is activated when the
temperature falls below a threshold which can be adjusted in the heater-
connection box. The heater coil works with 230 VAC voltage supply and needs
an extra power cable which is connected to the heater connection box
(see Figure 2).
4.2.3 RADAR Control and Processing Device and Transceiver
Figure 3: RCPD and Transceiver
The RADAR Control and Processing Device RCPD (see Figure 3) generates
the RADAR transmit modulation signal and passes it to the transceiver (see
Figure 3). It analyses the backscattered receiver signal, calculates Doppler
spectra and transfers average power spectra to
the MRR-PC where these spectra are interpreted. The RCPD has a water
protected IP65 housing which is fixed to the antenna arm (see Figure 3). At
the bottom side of the RCPD is the socket (see Figure 3) for the control cable
(see Figure 5)
service. As far as possible the RCPD should not be opened by the user.
