“…For example, when using a multipath radio channel, e.g., in MIMO systems [1,2], the number of radio paths is a priori unknown and should be determined. During the radar and acoustic-location (active or passive) observation, the case where the number of sources of the signals arriving at the antenna array is unknown is rather widespread [3][4][5][6][7][8][9]. However, the problem of estimating the number of signals has not yet been completely solved.…”

621.391Some algorithms for estimating the number of radio signals with known and unknown amplitudes and phases are synthesized and analyzed. Modified maximum-likelihood algorithms are used to obtain consistent algorithms for estimating the number of radio signals in the case of unknown amplitudes and phases. Efficiency of the estimation algorithms is quantitatively characterized by the abridged probability of the signal-number estimation error. The studied-algorithm parameters are optimized according to the analysis results.

“…In passive bearing estimation problems, the most common method is solving a nonlinear equation system for bearing (φ 0 ; θ 0 ) [1,8]. In this article, it is solved by minimizing the error function (Err) by the simplex optimization method [9]…”

Parabolic antenna reflector deformation caused by one-sided heating may be described by linear stretching model. The modeling of the influence of the antenna reflector stretching on the error in determining the bearing in the problem of passive monopulse direction finding was done. The method of electric axis displacement accounting was proposed and its feasibility was shown. The comparison of the probabilities of the bearing estimation with an error less than fixed threshold for the initial and refined radiation pattern was made.
