“…There are well-known approaches to partially solve the problems stated above. They consist of using radio signals with complex types of modulation [1][2][3][4][5][6], or combining single measurements from different radars [1], [7][8] in order to obtain a desired effect in a multi-position radar system (MPRS).…”

“…In this paper, an approach to solve the above contradiction is proposed. It involves using modular code binary sequences (CBSs) in radars with structures optimized by the criteria of secrecy and noise immunity [1], [4][5][6], but with ambiguous estimation of the radar-target distance. Additionally, the approach involves the joint processing of ambiguous measurements of each of the radars, and on this basis, getting unambiguous estimates of the target coordinates.…”

In this work, a two-dimensional analytical model of a multi-position radar system with ambiguous range measurements is elaborated and tested. In the proposed analytical model, properties of ambiguous measurements of fractional parts of relative unambiguity intervals in each radar are determined. Theorems are formulated defining the conditions of the unambiguous mapping of a target's coordinates onto the aforementioned fractional parts, as well as a reverse unambiguous mapping of those fractional parts onto a two-dimensional vector of integers. The vector contains ranges from the target to pairs of radars composing the considered system. The theorems are based on a principle of mapping the measurements of fractional parts onto a multidimensional unit cube, and the interpretation of the total set of measurements as a multilayer structure of this cube. Moreover, each layer is a multidimensional hypersurface bounded by the cube faces, and the unambiguity conditions are reduced to the conditions that these layers do not intersect with each other. Based on the developed model and the formulated theorems, an algorithm is proposed for disclosing the ambiguities of the fractional parts mentioned, as well as for obtaining unambiguous estimates of the target coordinates. An example of a multi-position radar system and results of modeling chosen elements of the algorithm for disclosing ambiguities are also presented. The aims of further research are formulated, particularly regarding the synthesis of multiposition radar systems and the elaboration of an analytical model for systems for the localization of emission sources of periodic radio signals.

“…A number of publications have been devoted to the search for compromises and appropriate methods and algorithms [9,10,13,15,16,[18][19][20][21][22][23]. Among them, the paper [10] proposes an approach that is based on the analysis of the structure of BS set using the theory of groups and algorithms such as "branch and bound".…”

Signal-code constructions with modulating binary sequences are widely used in multichannel radiocommunication systems, radar, and other information systems. Among these sequences, there are those that provide the minimum levels of side lobes of the aperiodic autocorrelation function and, accordingly, the required secrecy, noise immunity, resolution, and other important characteristics and parameters. The paper describes an alternative approach for solving optimization task that involves a complete full search for the optimal binary skew-symmetric sequences with odd dimension l using a criterion of minimum side lobes of the aperiodic autocorrelation function. The proposed method based on performing two consecutive steps: optimizing in the space of dimension L < 0.5(l − 5) of the objective functions with respect to the levels of side lobes of the aperiodic autocorrelation function and solving of an equation system which specifies the aperiodic autocorrelation function. The right sides of the equation system present the levels of the side lobes that are obtained as the result of completing the first operation. The developed methodology includes an analysis of the structure of sets of binary sequences; finding correlations between the structural components using the methods of group theory; establishing analytical forms that define the functional relationships between the levels of side lobes of the aperiodic autocorrelation function. The article presents an example of application and results of modeling of the offered algorithm to identify optimal binary sequences.
