| Subject: | TWP/CSAPR/I10 - PHIDP Incorrect |
| DataStreams: | twpcsaprsurI10.00, twpcsaprvertI10.00, twpcsaprsecI10.00, twpcsaprrhiI10.00
|
| Description: | The CSAPR software was found to have a bug in controlling its Automatic Frequency Conrol
(AFC) causing errors in PHIDP (specific differential phase). This is often exhibited by
the appearance of concentric rings in PHIDP where there are radar returns. |
| Suggestions: | Do not use PHIDP, there is no recovery of this data due to the software bug. |
| Measurements: | twpcsaprsurI10.00: - Unfiltered differential propagation phase shift(dp_phase_shift_unf)
- Differential propagation phase shift(dp_phase_shift)
- Specific differential phase(diff_phase)
- Unfiltered specific differential phase(diff_phase_unf)
