Robust design and analysis for opto-mechanical two array laser warning system
Abstract
In the past three decades, laser warning systems (LWS) have emerged in great importance, as the development of laser-guided weapons, such as airborne Hellfire missiles, has increased, posing an imminent threat to vital areas and VIPs. The laser warning station (LWS) can detect, classify, identify, and give alarm from laser threat at a very short time with high sensitivity. Therefore, the designers of this system must take into account the detectability and field of view to cover the area to be secured. The main contribution in this research is an analytical design of LWS that consists of 24 detector elements, distributed in two arrays (2 × 12) circularly. Also, calculating the best distance between the detectors according to the laser beam spot size. In addition, enhancement laser warring sensor detection capability and detection performance FOV between the detectors to increase coverage area up to 360°. Moreover, decreasing dead zone area between the laser detectors element. Mathematical calculations and illustrations made to reach the best systematic design.
