Comparison of Millimeter-Wave Cloud Radar Measurements for the Fall 1997 Cloud IOP
One of the primary objectives of the fall 1997 intensive observation period (IOP) was to intercompare Ka-band (35 GHz) and W-band (95 GHz) cloud radar observations and verify system calibrations. During September 1997, several cloud radars were deployed at the Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site, including the full time operation 35-GHz CART millimeterwave cloud ...
متن کاملestimation of carotid artery pulse wave velocity by doppler ultrasonography
background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...
متن کاملSimultaneous meteor echo observations by largeaperture VHF and UHF radars
We report simultaneous meteor echo observations using the Arecibo 430MHz and 46.8-MHz radars. Using identical data-taking and meteor selection criteria, 1868 and 367 meteors were found in the 430-MHz and 46.8-MHz beams, respectively, while 145 were found in both beams during the 7 hours of observation. Of the 367 VHF echoes, there were only 10 trail echoes, while the rest were head echoes, whic...

15 صفحه اولOn the Coherent Phase Noise of Millimeter - Wave Doppler Radar
The phase noise is a very important index to wireless system, especially in millimeter-wave continuous wave radar systems. The phase noise of the signal, which is firstly leaked from transmitter and then mixed to intermediate frequency band by the local oscillator (Tx-IF), will worsen the sensitivity of superheterodyne radar system used for Doppler velocity detection. In this paper, the coheren...
