The method of forming directional diagrams (RD) with the possibility of controlling it in space is described. The method of forming of the object location detection zone of complex shape in the transmitter-receiver optical system with the help of fiber-optic cables (OIC) is substantiated and created. The problem of a circular field of view of a multi-channel optoelectronic system (ECO) creating, designed for advanced high-speed objects at short distance detection has been solved. According to the results of laboratory tests of the developed ECO model is established that in the working range of distances of a location of 0,5 ... 10,0 m reliable detection of the target high-speed and high-precision registration of object in all DS directions is reached.

The high probability of recognition aircraft against the background of the sky and ground objects against the background of the underlying surface in real-time, as well as the high-precision definition of their spatial position in conditions of significant interference are an important area of application of IR electronic-optical systems [1].A complex that recognizes identifies and determines the spatial position of ground and aerodynamic objects, including small unmanned aerial vehicles, which monitor the underlying surface [2]. The complex features high speed and work in artificial and natural interference. The main elements of the complex are an optical channel, laser emitters and an actuator. The development of algorithms for the functioning of the complex, as well as circuit solutions, which will allow you to perform the tasks in the relevant modern level requirements, have been carried out.The complex includes the developed electronic-optical (laser) transducers of the infrared range, which form the probing pulses in the direction of the object under study, the detector of the maximum truthfulness of the target recognition with unknown range, speed and acceleration that, according to the specified algorithms, give the control command to the actuator [3]. The algorithms for making a decision on detecting and recognizing objects on the background of interference signals during sensing by a sequence of laser pulses, in which the criteria for the likelihood and artificial intelligence, are used. The main difficulty is to determine the set of signs of the reflected signal, according to which the object is recognition and the assessment of the parameters of ground and aerodynamic purposes. The space-time processing of signals is carried out, taking into account the specifics of the optical location information systems.An increase in the likelihood of target detection is achieved by using the principle of mutual compensation of spatially related active interference and optimizing the process of processing received information. Algorithmic methods have been developed to increase the recognition accuracy and reliability of the obtained results due to the use of measuring information obtained from the multi-element photodetector and the synthesis of algorithms with elements of artificial intelligence. To determine the object parameters on which recognition is performed, amplitude and phase spectra of reflected signals are used as signs.

An autonomous complex for tracking and controlling separation parameters has been developed, including the parameters of rotation, the spacecraft from the platform of the space level by a non-contact method using an optical-electronic, laser rangefinder and a computer program for calculating the current position of the spacecraft. The complex significantly expands the metrological provision of controlling the action of movable small-sized objects at the initial and final portions of the trajectory, which increases their reliability and correction ability.The hardware part of the complex consists of a three-channel optical-electron laser rangefinder system [1-3], which accumulates information on the parameters of the movement of a small-sized object located on the line of sight. The software, in conjunction with the external interface unit, allows you to record this information with the subsequent high-precision calculation of motion parameters for any current path of the trajectory [4][5]. The calculated information is displayed in numerical and graphic form, and is also illustrated by the behavior of the mathematical model in a different time scale. The main software modules and procedures are created in the Delphy software environment and work with real-time equipment. The output signals are transmitted according to the analog channels of the space level telemetry into the ground receiving center continuously. A developed computer program for calculating and visual display of the path of waste from the spacecraft from the platform of the space level is carried out in real time, recording the signals of the laser rangefinder of the complex directly from the instrument of telemetry for further processing. The program visualizes on the monitor screen the spacecraft motion on the selected time scale and calculates the current parameters for any of the points of the analyzed trajectory.Methodology has been developed to increase the accuracy and reliability of measurements of the distance by a non-contact method without interference in the process of relative movement of the mobile object and the software for dynamic measurements and the calculation of its spatial position.The designed complex determines the fact of separating the spacecraft from the platform, and also registers an abnormal change in the angular parameters of the waste

The optimization of the methods for the formation of the spatial-energy distribution of the probing radiation power and the processing the receiving signal by the locating laser information-measuring systems (LIMS), taking into account the spatial-temporal structure, is carried out, and the analysis of the existing methods of their processing is carried out too. An assessment of the integral criteria for the LIMS functioning when operating in conditions of interference has been made. The calculation of the parameters of the LIMS main links was carried out, taking into account the correlation between the resolution of the optical system and the capabilities of object detection, recognition and classification. A method was developed for the formation of the probing radiation density distribution and the receiving signal processing, taking into account its space-time structure, which made it possible to determine the optimal duration of the laser probe pulse. The determined duration makes it possible to eliminate errors in measuring the parameters of an object's movement under the influence of a combination of destabilizing factors and a lack of signal processing time, which will ensure the accuracy of the target detection and recognition.
