WebJun 15, 2000 · We report a significant improvement in the measurement of mesospheric winds using the incoherent scatter radar technique. With a height resolution of 600 m and a time resolution of 1 min, we show that the accuracy of the vertical wind measured by the Arecibo incoherent scatter radar is about 1 m/s in the altitude range of 68–88 km.
WebApr 11, 2024 · In such cases, incoherent components should be used to estimate the roughness. As it has been presented in Section 4.1, the coherent component and the total power waveform present a ~−9 dB consistent bias and an ubRMSD of 3.4 dB. Computing the roughness with coherent or incoherent components might impact a bias in the retrieved … http://rsss.ece.illinois.edu/sites/rsss.ece.illinois.edu/files/B3cscatter%20copy.pdf
