Abstract
The photoelectric reconnaissance and detection is the precondition of implementing efficient photoelectric jamming and the important link of electro-optical countermeasures. Starting with the features of laser signal and the characteristic of laser detection device, the limited factors of faint laser detecting technology in application were analyzed, which include the contradiction between of receiving in large field of view and the technology of narrowband spectrum filtering, the contradiction between clear aperture of optical system and angle of view, the limitation of low repeat frequency rate of laser and the limitation of narrow pulse of laser signal. At the same time, the key technologies of faint laser signal detection were analyzed, including detection of faint signal, eliminating parasitic light, high gain optical antenna and protecting detector. What’s more, the application modes in direct detecting laser warning device and scatter interception laser warning device were analyzed.
