Currently, one of the topical issues arising in the functioning of radar stations for various purposes is the issue of tracking complex targets, namely the case of crossing the trajectories of several observation objects. When intersecting trajectories of objects, there is uncertainty in the presence of numerous elevations caused by reflections from a plurality of reflecting surfaces or areas of space, which leads to entanglement of trajectories, that is, the detected object is accompanied by a radar along the trajectory of another object. It is also possible to trace the second object along the trajectory of the first. This case is a special difficulty, as it leads to maintenance disruptions, loss of objects and their omission. At the same time, at the classification stage, an object can be assigned to a class to which it does not belong. Therefore, how to achieve a reliable classification of objects requires the development of methods for assessing its performance. To do this, a scientific and methodological apparatus for checking the quality of radar operation was developed (in which only trajectory information was analyzed at the first stage, and joint analysis of trajectory and polarization information was carried out at the second stage), which is a simulation model implemented in the software environment MathCad 15.0. The simulation results show that with an increase in the number of tracked objects and a decrease in the distance between them, the value of the classification quality indicator decreases. This indicates a contradiction between existing processing methods and classification quality requirements and indicates the need to develop new methods that provide a given quality indicator. A possible tool to resolve the contradiction may be the use of polarization information in order to ensure the required probability of correct classification of objects, namely, when identifying elevations and extrapolating trajectories at the stage of tracking objects of observation. In order to solve the problem, the initial data for the model of classification of objects were polarization scattering matrices, on the basis of which polarization parameters were calculated and object features were formed. The results of the simulation show that the use of polarization information when tracking a large number of objects (from 10 trajectories and their intersection) provides the required level of classification quality for existing algorithms. The increase in the probability of correct classification ranged from 8% (at the edges of the radar viewing area) to 12% (in the center of the directional pattern).

The results of studies evaluating the influence of various visual features of a sighting target on the probability of its detection by an optoelectronic device are presented. The purpose of this study is to identify the most significant visual features of the sighting target, which contribute to reducing the probability of false recognition of foreign objects with similar features by an optoelectronic device. For this purpose, the influence of such features as the color, shape and frequency of flashing of the sighting target was evaluated. According to the results of the research, it is concluded that the combination of the considered visual features provides a high probability of detecting a sighting target even in conditions of insufficient visibility and contributes to an increase in the range of its detection.

The article deals with the issue of stealth of radio-electronic means, energy and structural, radio-electronic masking and ways of its implementation. The structure of the unknown signal for exploration and its parameters, as well as the a posteriori probability of each signal associated with the a priori likelihood function and the cases of its solution. The advantages and disadvantages of broadband signals and their characteristics used in modern radars are considered. On the basis of which conclusions are drawn: LFM radio pulse and a single FCM pulse, used in target tracking modes, has high resolution capabilities in range and radial velocity. The ACF of the FCM pulse has side lobes that raise the target detection threshold, as a result of which radar targets with a weak echo signal can be missed. The considered signals do not provide energy and structural stealth of the radar operation.

The mode of selection of ground moving targets is one of the main modes of operation of the radar observation of the underlying surface. The article discusses the features of processing a trajectory signal when detecting moving targets in a radar with synthesizing the antenna aperture due to the rotation of the real antenna phase center. To compensate for the distortion of the trajectory signal arising from the movement of a target, an algorithm is proposed for estimating the Doppler shift of the signal frequency reflected from a moving target, with its subsequent compensation.
