Maini PY - 2007/07/01 Y2 - 2024/03/29 TI - High-angular Resolution Laser Threat Warner JF - Defence Science Journal JA - DSJ VL - 57 IS - 4 SE - Aeronautical Systems DO - 10.14429/dsj.57.1783 UR - https://publications.drdo.gov.in/ojs/index.php/dsj/article/view/1783 AB - In this paper, the design and development aspects of a high-angular resolution laser-threat Warner developed at the Laser Science & Technology Centre (LASTEC), Delhi are presented. It describes a high-angular resolution laser-threat warner capable of giving warning with a resolution of i 3" when it is exposed to laser radiation from visible and near-IR pulsed solid-state laser source. It has a field of view of 90' in the azimuth direction, whereas the elevation coverage is between -5" and + 25". It is capable of handling multiple types of laser threats covering wavelength from 400 nm to 1100 nm and has an operational range of 4 km for a Q-switched laser source energy (10 ns) of 10 mJ/pulse and output beam divergence of 1 mrad. The paper also describes its simulated evaluation process and field-testing which it has undergone. The result of field-testing confirms that it meets all its performance specifications mentioned above. ER -
