Appearance of the ground-based PAOLS model
Optomechanical scanning system
|
Purpose
The PAOLS experimental models implement the following functions:
1) search for targets by positive or negative radiation contrast;
2) active add-on reconnaissance of the detected targets directly in the course of a passive search;
3) cyclic tracking of targets;
4) exact three-coordinate tracking of targets.

PAOLS features
The PAOLS functions (listed above) are implemented by an optomechanical program-controlled system. Its kinematic scheme allows one
to implement an IR direction-finder with a panoramic observation system with helical scanning of the area under control and of an
IR direction-finder with FLIR for radial scanning of the area under control. The optomechanical unit also includes a built-in laser
radar which shares a common optics with the IR direction-finder and which is operated by the signals coming from the output of the IR direction-finder.
