Abstract

The invention discloses a semi-active laser detection method and system. The method comprises the steps that a laser reflection signal of a guided weapon attack target is collected and converted intoa first voltage signal; the first voltage signal is adjusted into a second voltage signal through a gain value of an automatic gain control amplification circuit; whether the collected laser reflection signal is valid or not is determined according to the second voltage signal; the second voltage signal is converted into a digital signal through A / D conversion on the condition that it is determined that the collected laser reflection signal is valid; and lastly, the yaw angle and the pitch angle of the attack target are calculated according to the digital signal, and the position of the attacktarget is determined. According to the semi-active laser detection method and system, the technical problems that in the related technology, components in a strapdown laser seeker detection assemblyare discrete and high in cost are solved, and the technical effects of being simple in structure, low in cost and good in compatibility are achieved.

Description

technical field [0001] The invention belongs to the field of guided weapon control and relates to a semi-active laser detection method and system. Background technique [0002] Precision-guided weapons have become one of the indispensable strike means in today's information warfare, among which laser-guided weapons have become the weapons and equipment that various countries are vying to develop in recent years. Semi-active laser guidance technology is widely used in various conventional weapons such as missiles, rockets, and bombs because of its high strike accuracy, low cost, flexible operation, and simple structure. [0003] In related technologies, the strapdown laser seekers commonly used in China have problems such as weak anti-backscattered light ability, low angle measurement accuracy, and confidential internal mechanism, which cannot fully meet the overall use requirements of precision-guided weapons. For its key technology, domestic manufacturers mostly use multip...
