Performances of Multi-channel Commander's Sighting System for Military Land Vehicle Application

摘要

The developing multi-channel stabilized commander's sighting system which can be operated by day and night consists of 2nd generation LWIR thermal imager, daylight TV camera, eyesafe 1.54 μm Raman shifted Nd:YAG laser rangefinder and direct view telescope for outstanding observation and fire control capabilities. The high performance thermal imager which uses a 480x6 HgCdTe array detector has dual field of views such as 3x2.25° in NFOV and 10x7.5° in WFOV. Daylight TV camera which employs 768x494 color CCD has 4.0cycles/mrad resolution and the same dual FOV. For an eyesafe operation, 1.54 μm Raman shifted Nd:YAG laser rangefinder with InGaAs APD detector is incorporated into direct view optics to provide range data to commander and fire control computer with an accuracy of 10 meter. Multi channel EO/IR sensors for day and night views are integrated into the stabilized head mirror. In this paper, the performances of multi channel EO/IR sensors for the commander's sight has been analyzed for a tactical ground application.
