Figures 8-1 and 8-2, and Table 8-1.)
The WR-800 Receiver Transmitter (RT) generates and receives X-band radio
frequency energy for the purposes of weather detection and ground
mapping. The 9345 *3O MHz transmitted signals are sent to the antenna
via a waveguide transmission line.
Echo signals received by the antenna
are routed through the waveguide to the RT and then to the receiver. The
receiver processes the signals, encoding them into one of four levels,
depending on their intensity, scan converts them, and enters them into
the random access memory. This memory is read in raster scan format, and
its output is delivered to the indicator and electronic flight
instruments.
