RESEARCH ON THE EFFECTIVENESS OF LASER RADAR (LADAR)
(pp.68-72)

Abstract. The article is devoted to the study of the influence of the atmosphere on the effectiveness of the monostatic multipurpose laser radar (ladar). In this case, there are fluctuations in the laser beam, in size, position, and intensity distribution. The injury of the ladars laser beam is explained by such effects as absorption, scattering, turbulence, and nonlinear thermal effects. Also relevant are issues such as the influence of inclined laser propagation paths and the angle of beam impact on the reliability of the measurement result, which is important in laser systems for aerospace applications. Investigation of effectiveness of ladar functioning upon effects of above factors. First, the case of single-purpose and then multiple use of laser radar for various targets located at different, specially specified distances from the radar is considered. As a result of such a consistent consideration of the research object, the task of optimizing the multi-purpose operation of a ladar is actualized. An optimization method is used based on the apriori acceptable assumption that the technical resource allocated for the implementation of a multi-purpose detection mode for objects located at different distances is limited. A technique has been developed to identify possible extreme operating modes of a monostatic multipurpose laser radar. Taking this limitation into account, the problem of variational optimization of a multipurpose monostatic ladar) is formed, a discrete optimization objective functional and its analog equivalent are constructed. Solving the optimization problem by the Euler method made it possible to determine the existence of an extreme mode of radar operation in a multi-purpose mode. The solution to the optimization problem made it possible to specify the type of extremum as a minimum. On this basis, it is concluded that it is necessary to avoid in practice the implementation of the discovered extremely undesirable mode of multi-purpose radar implementation.

Keywords: laser radar (ladar), efficiency, optimization, multi-purpose mode, methodology.
