The Model for Forming the Flight Profile of an Aircraft Using Dynamic Programming Tools 53_10.pdf

The article deals with the process of forming the flight profile of an aircraft. Calculation and selection of the optimal flight profile of aircraft are some of the most common issues in the tasks related to the planning of aviation operations. The flight profile in the coordinates ‘range-altitude’ is a sequence of areas each of which corresponds to a specific program for changing altitude and speed. The construction of the flight trajectory of an aircraft is characterized by the work with a large number of nonlinearly varying dependent parameters and taking into account the restrictions imposed on flights: the permitted echelons of aviation flight altitudes, forbidden zones with unacceptable meteorological conditions, forbidden zones of action of enemy air defenses. These factors make it very difficult to model the specified process. The application of the mathematical apparatus of dynamic programming in solving this problem can allow the most efficient choice of flight modes of aircraft and optimize the process of forming the flight profile as a whole.

Building Maneuvering Targets Trajectories on the Basis of Splines and Kalman Filters 000_8.pdf

The algorithms of tracking radar targets on the basis of Kalman filtering and smoothing splines allowing to estimate target motion parameters in the absence of accurate information about the dynamic model are considered. The comparative analysis of algorithms effectiveness for different types of trajectories was carried out. It’s well established that in case of intensive maneuvering and quite accurate initial measurements, the algorithms on the basis of splines (approximation of the curve with the use of spline functions) are subjects to a little uncertainty, simple to software implementation, moreover, they do not require a lot of computational resources. Simultaneously, preference should be given to Kalman methods (recursive functions estimating the state of the dynamic system) for smoothly varying trajectories with known statistical parameters. Under conditions of uncertainty relative to dynamic parameters of the target, many-model multiversion procedures for trajectory construction are proposed. Experimental results were obtained on the basis of the radar situation simulation. The results allow to confirm working ability and the efficiency of algorithms and software developed.

Mathematical Modeling and Research of Filtering Algorithms While Target Data Tragectory Processing 39_5.pdf

The tracking of a maneuvering target in automated systems is a quite difficult task. A sudden change in speed of a target or change of its movement direction can have a major effect on the result of target movement parameters filtering. There are some methods of target movement characterization in statically indeterminate situations, at which conformities between measured and real objects positions are unknown, such as algorithms using Kalman Filter, multimodel filtering algorithms, and algorithms of intermodel interaction. The goal of this article is a research of algorithms for preliminary processing of target trajectories experimental data, intended for smoothing random interferences. The algorithm based on the spline smoothing function constructed by several trajectory points is also offered to be used to increase accuracy of maneuvering trajectory estimation in target tracking. This algorithm makes it possible to evaluate the intensive change of target movement parameters in case the dynamic movement model is not available, based on measured data and its approximation. The simulation of target movement parameters estimation algorithms proves that this algorithm provides a more exact result in comparison with algorithms using Kalman filter. In addition, this algorithm is quite simple to implement and requires not many computational resources. This algorithm can be used together with multimodel radar data processing algorithms.

The Multi-model Data Processing Algorithms of the Mobile Radar System 38_1.pdf

The creation features of trajectory processing algorithms for mobile multi-position radars and the software complex for 3D-simulation of a situation, radar surveillance and data exchange (virtual polygon) processes are considered. The combining data and the trajectory processing are carried out based on multi-model procedures of a simultaneous distinction and evaluation of dynamic vector parameters.To examine and debug algorithms, designed for the trajectory processing, a software virtual polygon is developed, which provides a virtual 3D-polygon modeling, including local objects and maneuvering targets, as well as the processes of information acquisition and processing with a given number of mobile radars of various types. The documented materials of all the major processing stages of the observation results of two ‘Reka’ type radars are presented explanatorily. In addition, three models of the objects motion with different dynamic properties are simulated. The developed methods, algorithms, and software can be taken as a basis for the creation of advanced systems designed for the processing of a large number of interacting mobile multi-position radars.
