Mountain wave motions determined by the Esrange MST radar
A European campaign of ground-based radar, lidar and optical measurements was carried out during the winter of 1996/1997 (28 December±2 February) to study lee waves in the northern part of Scandinavia. The participants operated ozone lidars, backscatter lidars and MST radars at ALOMAR/Andoya and Esrange/Kiruna, and an ALIS imaging system in Kiruna. The Andoya site was generally windward of the ...
متن کاملWavelet Denoising Techniques on MST radar Data
The aim of the work reported in this thesis is to develop wavelet based denoising technique for MST radar data. It was proposed to achieve this by first designing a wavelet suitable for clear-air echoes and then optimizing the denoising technique to suite MST radar data. While the details of the wavelet design for MST radar data is presented in the Chapter 4, the optimization of denoising techn...
متن کاملMF radar observations of mean winds and tides over Poker Flat , Alaska ( 65 . 1 ◦ N , 147 . 5 ◦ W )
MF radar wind measurements in the mesosphere and lower thermosphere over Poker Flat, Alaska (65.1 N, 147.5 W) are used to study the features of mean winds and solar tides. Continuous observation with the newly installed radar is in progress and in the present study we have analyzed a database of the first 27 months (October 1998–December 2000) of observation. The observed mean wind climatology ...

متن کاملDetection of MST Radar Signals
An efficient algorithm based on Empirical Mode Decomposition (EMD) de-noising using soft 10 threshold techniques for accurate doppler profile detection and Signal to Noise Ratio (SNR) improvement of 11 MST Radar Signals is discussed in this paper. Hilbert Huang Transform (HHT) is a time-frequency analysis 12 technique for processing radar echoes which constitutes EMD process that decomposes the...
