| Subject: | SGP/WACR/C1 - PRF Change from 10 kHz to 5 kHz |
| DataStreams: | sgpwacrC1.b1, sgpwacrC1.00, sgpwacrspecmomC1.00 |
| Description: | Due to a modulator overheating problem, the pulse repetition frequency (prf) was changed from 10 kHz to 5 kHz to reduce the transmitter duty cycle. This results in a change of the Nyquist velocity from 7.9 m/s to 3.8 m/s. |
| Suggestions: | If precipitation Doppler velocity is greater than 3.8 m/s, it will "fold over" and extra efforts must be undertaken to adjust for this. ARSCL handles this automatically. |
