Estimation of Target Elevation Angles in Meter Radars
... the estimates of the target site angles. The possibility of solving the problem of estimating the angles of the target site by three methods is analyzed: the method of angular spectral analysis, the method based on the likelihood equations, the method of maximum likelihood with high resolution, developed at the IKBFU. On the basis of the likelihood functional, expressions are derived that define the radiation patterns of the antenna system and the surface of the likelihood functional. Results of model researches ...
The filtration radio pulse maximum likelihood method
This article presents a solution to the problem of resolution of two radio impulses through the maximum likelihood method. The authors have obtained expressions for the optimum processing of a set of two radio impulses in the domains of their orthogonality and non-orthogonality, as well as expressions for the dispersion of radio impulse parameters (Rao-Cramér dispersion)....
Search algorithms for an extremum in the maximum likelihood method

A comparative evaluation of the correlation analysis and maximum likelihood method resolution in the reception of phase-shift keying signals based on Barker codes
This article presents the results of a MATLAB-assisted study into the maximum likelihood method resolution in the reception of two radioprobing signals based on Barker’s codes. The study is based on the expressions ob-tained by the authors within optimum reception theory that make it possible to carry out a joint evaluation of the same ...
Application the theory of an optimum detection for a spatial resolution of signals
The article deals with application of the theory of optimum detection to the azimuth resolution of two sound sources. This paper compares the solutions based on maximum likelihood method with the classical approach (Rayleigh's approach). Furthermore, the computer model and the testbench (experimental apparatus) have been created for an extensive analysis of the obtained solution. Our experimental and model results demonstrate a ...
The maximum likelihood method as applied to chirp signals
This article presents signal processing through linear frequency modula-tion (chirp signals) using the maximum likelihood method. The authors have obtained main expressions describing the optimal algorithm for processing these signals, as well as expressions for chirp signal dispersion (Rao-Cramér dispersion). The article presents key findings of model calculations during ...
