The KVL-B complex is an information management system that operates within an electro-optical system for identification of interferences and is designed to detect laser light and lay smoke or аеrosol screens to disorient enemy-guided missiles. The complex includes a set of КVLB pulsed laser detectors that operate within the extended spectral range from 0,6 µm to 12 µm.

The system is compatible with the 1A45 or 1A40 fire control system. It is mounted in T-84 tanks, BМ «Оplot», T-72 tanks, and other armored, special-purpose vehicles, including APCs, BMPs, and armored vehicles.

Features

The complex works in the extended spectral range of 0.6 … 12 μm, which includes all wavelengths of laser devices (rangefinders, target seekers, illuminators, etc.) that are in service with the russian federation and the leading countries of the world
Operating modes – 6:
- аutomatic (АUTO)
- semi-automatic (SA)
- аutomatic with turret turning (A-SHIFT)
- turning and firing an existing grenade in the direction of the operator’s field of view without irradiation (TD-SS)
- simultaneous firing of all existing grenades upon the operator’s command (Group)
- system functioning control (Control)
The complex contains a built-in control system
Built-in control with and without commands issued to the actuators
Ability to transfer data to the on-board computer
Immunity to high shock and vibration of the complex components
Waterproof
The system meets the requirements of group 1.10 in accordance with GOST B 20.57.304 standard, climatic performance UKhL (regions with a moderate and cold climate) in accordance with GOST 15150 in terms of resistance to the influence of climatic and other factors of the environment

Purpose Of Use

Detects laser light by laser guidance facilities of the enemy
Identifies an irradiator type (a rangefinder, a target seeker, or an illuminator)
Generates a signal notifying the crew of an object’s exposure to laser guidance facilities of the enemy
Determines the direction towards the laser source
Controls aerosol grenades that are shot back to the direction of detected laser radiation for laying a screen in order to disrupt aiming

Application

The complex is mounted in armored special-purpose vehicles, including tanks, APCs, ВРМs and armored vehicles
When laser irradiation is detected the complex determines:
- the type of irradiation (rangefinder or illuminator)
- the direction of irradiation
- availability of loaded launchers
- the firing angle of the smoke grenade, taking into account its speed, direction, and wind speed
- In <<АUТO>> mode – fires existing grenades without turret turning
- In <<А-SHIFT>> mode – turns the turret to the smoke grenade and fires one or three grenades (main, 1^st additional, 2^nd additional)
- <<SA>> mode – is similar to <<A-SHIFT>> mode. Start of the mode by pressing – the <<Start>> mode
- <<TD-SS>> mode – turns and fires the existing grenade in the direction of the operator’s field of view without irradiation. Start of the mode – the operator’s command
- In the <<Group>> mode – simultaneous firing of all existing grenades upon the operator’s command
- In the <<Control>> mode – system functioning is monitored
