Passive detection and target tracking
The
purpose of the Long Range Thermal and Video Imager is to detect,
identify and track the target from very long distances. The Imager
operates properly in any weather conditions during the day and at
night. The target image is displayed on LCD at every stage
of tracking.
The Imager consists of a thermal camera, a
television camera, cables, control system and LCD display panel.
The Long Range Thermal and Video Imager in
particular proves functional for the following air defense
systems:
It replaces the former imager and effects
thermal target detection as well as increases the range of
detection. The Imager reduces radar radiation; thus, increases
radioelectronic camouflage.
The Long Range Thermal and Video Imager can be
adjusted to any air defense fire control platform systems.
The thermal camera, the display and the data
display mode are selected in accordance with the client's
individual demands and the conditions of the Imager prospective
performance.
The
long-range television camera allows observing remote targets
within the range of visible light in the conditions of minimum
lighting. It is furnished with an advanced zoom lens and
supplies a video signal to the indicator in the CCIR standard.
The long-range thermal camera serves the purpose
of surveillance of distant 
objects
in the air. It allows detecting and observing the target
independent of lighting conditions both during the day and at
night. As an element of the Long Range Thermal and Video Imager, a
thermal camera can be used operating in the spectral range of 8-12
mm or 3-5 mm, whose range under standard weather conditions
exceeds 40 km.
The display unit with LCD composed of:
- the image display made in the technology of
the active LCD matrix,
- microcomputer, renders imaging from the
television camera or thermal camera.
In the
air defense missile systems the display unit serves as the
integrated indicator displaying data from other tracking channels,
such as radar stations. On the microcomputer-generated image with
the target parameters, i.e., azimuth, elevation, altitude and
distance, an image from the Imager is displayed.
