Task configurations

You can customize and add to the default task configurations.

Note the following guidelines when creating or modifying tasks:

  1. As it is not possible to get the best velocity and reflectivity data at the same time, default tasks are divided as follows:
    • Long-range surveillance with coarse spatial resolution for detecting weak echoes (SURVEILLANCE task).
    • Medium-range polarimetric volume with good spatial resolution for high quality reflectivity and polarimetric data (VOL_A and VOL_B tasks).
    • Short-range volume with good spatial resolution for high quality velocity data (WIND task).
  2. To maximize signal processing data quality, all tasks use 2-byte data in the radar server computer.

    By default, all RAW products are truncated into a 1-byte form for transmission. If the bandwidth allows, use 2-byte data in RAW products.

  3. After installing and calibrating the radar system or if you change the default task processing parameters, you must adjust the quality threshold values.

    For example, if you increase the number of samples, enter a slightly decreased LOG value to improve measurement sensitivity.

  4. The tasks use Doppler filter number 4, which is a Gaussian adaptive (GMAP) filter with a 0.4 m/s width.

    Depending on the clutter conditions, test a weaker filter (number 3 or smaller) or a stronger filter (number 5 or greater) to find the optimal filter for your radar site. All the tasks use a CSR threshold of 40 dB.

    Depending on the clutter conditions, you can test a stronger value (less than 40 dB). Before finalizing the setting, measure with real weather to verify that the weather echoes near zero velocity do not vanish (Doppler snake).

  5. To benefit from the enhanced sensitivity of the polarimetric signal processing, use the Ze data moment to generate echo products.
