Operating Manual
Data Acquisition
The data acquisition system controls not only the reception of radar data from the
receiver but also the generation of pulses to the transmitter.
Transmitter control is preset to the following:
Pulse width – 4 uSec
Pulse repetition frequency – 1000 Hz
There is a preset number of conversions accomplished by the ADC system within
this module. Each of two channels pulls in 16-bit conversions and passes them to
the FPGA for processing.
Significant filtering is accomplished within this module to reduce the noise level of
the radar system to a minimum. This allow for a significant increase in sensitivity.
Data from this module is sent to the host computer for further processing and
product generation
These products include:
Reflectivity
Storm intensity is displayed in a standard dBz color palette for PPI, Scan and
RHI displays
Velocity
Storm velocities are displayed in a standard m/s display. The presence of
tornadic activity as well as high levels of turbulence can be detected here.
Particle Identification
This product includes a color-coded display showing ice, snow, rain, hail, sleet,
graupel and several other particle types. The display colors are labeled
accordingly.
