The Eithth International workshop on technical and scientific aspects of MST Radar -mst8- will be held Monday through Saturday, December 15-20, 1997 in the South Indian Garden City of Bangalore
The major topics of the workshop - mst8 - deal with radar scattering processes in the atmosphere and ionosphere, winds, waves and turbulence in the lower and middle atmosphere, meteorological phenomena and applications, such as wind profilers, boundary layer radars and networks, as well as major scientific, technical and signal processing achievements and highlights from the MST radar facilities of the world. These workshop is is organised into four major sessions as specified in the ensuing page. A visit to the National MST Radar Facility(NMRF) in Gadanki near Tirupati will be arrange on Saturday, December 20, 1997.
The International Steering Group consists of Prof. Shoichiro Fukao (Radio Atmospheric Science Center, Japan), Prof. Miguel F. Larsen (Clemson University, USA), Prof. C.H. Liu (National Central University, China-Taipei), Dr. A.P. Mitra (National Physical Laboratory, India) and Dr. Jurgen R(tger (EISCAT Scientific Association, Sweden). The local organization is under the direction of Prof. P.B. Rao (National MST Radar Facility, India) and Dr. S.C. Chakravarty (Indian Space Research Organization).

The method adopted for processing spectral data is central to the problem of extracting information from the MST radar signal in an environment of low signal-to-noise ratio(SNR). In this paper we present a method implemented at the National MST Radar Facility, Gadanki, which operates in an adaptive way for tracking the Doppler signal and computing its moments.
The major data processing steps involved in the method are: (1) After editing the raw data for any interference that might be present, the average noise level is estimated for each range bin using the objective method of Hildebrand and Sekhon (1974) and subtracted from the power spectrum. (2) The total range is divided in to specified number of windows and for each window the following criteria are setup for adaptive tracking of the signal from range bin to range bin: (a) Doppler Window, (b) SNR threshold and (c) maximum wind shear. (3) Five candidate spectral peaks are selected within the specified Doppler window for each range bin SNR threshold and accepted if the criterion is satisfied. (4) For those range bins for which the SNR criterion is not met, the most prominent candidate signals bins that still remain unrepresented are filled in through interpolation of the spectral moments computed for the closest range bins.
The parameters used for the three criteria are so adjusted as to provide the best fit Doppler profile as judged by the visual inspection. The adaptive algorithm has been applied to a wide variety of signal conditions and its advantages over the conventional non-adaptive algorithm in estimating spectral moments, particularly over the height range of low SNR, have been demonstrated.

How to reach Bangalore: Bangalore is well connected to all the port of entry to India such as Mumbai (Bombay), Chennai (Madras), Delhi and Calcutta. One of the major domestic airlines - The Indian Airlines operates regular services from these four metropolitan cities. However, a few private airlines also operates regular schedules to Bangalore.
The schedule of Indian airlines and Jet Airways for internal travel will be included in the second circular being sent through regular mail.
A magnificent post-independence structure incorporating the traditional features of architecture, Vidhana Soudha is located in Cubbon Park. Built in granite, this three story building now houses the state legislature and secretariat. Prior permission is necessary to visit the interior.
Bannerghatta National Park:
About 23 km from Ashok, a fast developing extensive reserve for wild life covering an area of 104 sq.km. Apart from enclosures for different animals and birds, the park has a lion safari and a crocodile farm.
About 6km from Ashok, this garden was laid out by Haidarali and further developed by his son Tippu Sultan more than 200 years ago. Today it is one of the best Botanical Gardens in the country, spreading over 240 acres with over a thousand different varieties of trees and plants.
Fort and Tippu Sultan's Palace:
About 7km from Ashok, this historic fort was originally built in mud by Kempegowda, a local chieftain in 1535. Rebuilt in stone two centuries later by Haidarli, it was further improved by his son Tippu Sultan.
Government Museum and Venkatappa Art Gallery:
About 5 km from Ashok, situated next to Cubbon part on Kasturba Road, the museum displays sculpture, coins inscriptions, paintings excavated items, bronzes etc.
Visveswaraiah Industrial & Technological Museum:
About 3 km from Ashok, next to the Government museum on Kasturba Road, it is dedicated to the memory of M.Visveswaraiah, the architect of modern Karnataka. The exhibits highlight the various applications of Science & technology in industry and human welfare.
