Confluence Retirement

Due to the feedback from stakeholders and our commitment to not adversely impact USGS science activities that Confluence supports, we are extending the migration deadline to January 2023.

In an effort to consolidate USGS hosted Wikis, myUSGS’ Confluence service is targeted for retirement. The official USGS Wiki and collaboration space is now SharePoint. Please migrate existing spaces and content to the SharePoint platform and remove it from Confluence at your earliest convenience. If you need any additional information or have any concerns about this change, please contact myusgs@usgs.gov. Thank you for your prompt attention to this matter.

v = velocity recorded by the radar, feet per second; fps

fDoppler shift = Doppler shift associated with tuning fork frequency, MHz; Hz

c = speed of light, miles per second, ; mi/s

fradar = radar frequency, MHzgigahertz; GHz

Given,

fDoppler Shift = 1055 MHz Hz tuning fork frequency, MHz

c = 186,000 mi/s

fradar = 24.150 GHz

v = 1055 MHz Hz x 186,000 mi/x 5,280 ft/mi/(2 x 24.150 GHz x 10Hz/1 GHz)  =  21.5 fps          Eq. 3
