Методика визначення енергетичних характеристик лазерної системи постановки перешкод засобам ураження з тепловізійною системою наведення

Abstract

The article proposes a methodology for determining the energy characteristics of a laser countermeasure system against weapon systems equipped with a television guidance system as part of the protection system of armored combat vehicles. The objective of the study is to develop an analytical framework that enables the substantiation of the parameters of a laser countermeasure system required to ensure disruption of the guidance process. To achieve this objective, the following tasks were addressed: formalization of the operating conditions of the system “armored combat vehicle with a laser countermeasure system – weapon system with a television guidance system”; identification of a set of interrelated input and output parameters that define the requirements for the laser countermeasure system; and establishment of an analytical relationship between the spatial–energy characteristics of the laser beam, the parameters of the aiming and stabilization system, the relative geometry of the interacting objects, atmospheric conditions, the characteristics of the receiving optical system, and the quantitative indicators of photon–electron and thermal processes in the optical sensor.

Based on a generalized description of the interaction between laser radiation and the television camera of a weapon system, analytical relationships were obtained for determining the energy delivered to the sensor, the number of generated electrons, and the thermal energy in the photosensitive layer. The proposed relationships constitute the computational core of the methodology and enable the transition from formalized operating conditions to the substantiation of rational energy parameters of the laser countermeasure system and to the quantitative assessment of the feasibility of its integration into the protection system of armored combat vehicles.
