The use of spatially separated radars for solving the problem of selection


K. Yu. Sergunov

Because the targets interception is carried out at extreme speeds anti-aircraft guided missiles (SAMs) in conditions of severe shortage of its energy, it is essential to conduct selection for exo-atmospheric flight phase or segment with a highly rarefied atmosphere, which creates some leeway for the organization firing targets. However, this is the most difficult part of the trajectory to solve the problems of selection. Conditions of observations on it are such a complex target that we have to take into account the possibility of hundreds, and sometimes thousands of decoys, cover up the true purpose. Feature of the radar when observing objects at long range is the limitation achievable spatial resolution in practice. Thus, the use of radar stations in solving the problem involves the selection of targets: the ability to collect data when accompanied by goals and solving the problem of selection in a short period of time; the presence of a feature vector to solve the problem of selection, in principle sensitive to the observation of the true or false targets. The aim of this paper is to study the possibility of using multi-position information from radar systems offline for breeding purposes and elements of quantitative estimates of the effectiveness of the proposed solutions breeding purposes elements. Several features which estimation usually involves serious technical problems can uniquely and reliably distinguish true target in a complex target. These symptoms may be treated as sufficient. Other features, which evaluation can be carried out much simpler information for unambiguous solutions are not, however, they can add significantly to the solution formed on the basis of a count attributes. The key elements include the selection of the mass of the object, the fact that the stabilization rotation (angular velocity of the center of mass), the fact of the secondary X-rays [1]. Additional features of selection are attributed trajectory characteristics, dimensions of the object dalnostny portrait of the object (the impulse response of the object) and the luminosity of its own projects in different regions of the electromagnetic spectrum [1].
