Description (optional)
Deploying aircraft in field campaigns is resource-intensive and expensive. It is therefore important to make the best use of the deployed instruments by optimizing the data collection process. The HIAPER Cloud Radar (HCR), a 94 GHz W-band radar, is requestable by the scientific community for field campaigns on the NSF NCAR Gulfstream V HIAPER aircraft. It has been deployed in five major field campaigns, spanning from the Southern Ocean to the tropics of Central America. Recently, enhancements to the capabilities of the radar were made by upgrading the hardware for signal processing.To optimize data collection, the HCR team developed a new pulsing scheme which allows for the interleaved transmission of long and short pulses. This pulsing scheme provides the benefits of both pulse lengths without having to compromise by choosing one only. Long pulses increase the sensitivity of the radar and extend the maximum range, while short pulses provide observations with higher range resolutions. Coupled with the dual pulse lengths is dual pulse repetition time (PRT) operation, which aids in velocity dealiasing. A merging technique was developed, which combines the long- and short-pulse observations into merged radar moments fields. Observations collected in a testing project on the ground indicate that the new pulsing scheme delivers the increase in sensitivity predicted by theory while retaining high range resolution.
