Description

Three approaches to improving the effectiveness of monitoring of dangerous meteorological phenomena are considered. The first one is based on the modernization of incoherent weather radar on the example of MRL-5 for the possibility of estimating the width of the doppler spectrum by implementing algorithms for pseudo-coherent frequency signal processing with subsampling. Mathematical modeling is carried out, confirming the technical feasibility of the algorithms. On the basis of mathematical analysis, expressions are obtained and graphs of the suppression coefficient of the moving target selection system are presented. The second approach offers a way to improve the efficiency of monitoring for turbulence. An algorithm for detecting zones of increased turbulence and estimating their parameters is proposed. Equations are obtained, on the basis of which algorithms for detecting and estimating the normalized width of the doppler spectrum of zones of increased turbulence, as well as determining the power level of the reflected signals, are synthesized. The third approach describes a way to improve the efficiency of thunderstorm detection and the accuracy of their localization by supplementing the MRL-5 with magnetometric equipment. An example of the implementation and brief technical specifications are given. (paper)
