Problems solved by technology

If there is a natural background similar to the target size near the attacked target, such as small buildings, bushes, small trees, etc., if the laser fuze detects it first, it will also send out a detonation signal, resulting in false bombing and affecting the attack effect of the missile.

Embodiment Construction

[0011] specific implementation plan

[0012] The present invention will be further described below according to accompanying drawing.

[0013] As shown in the figure, the laser is an important component of the laser fuze test. It is required that the laser emitted by the laser of the test equipment should have the same frequency as the laser on the bomb. In the 6 test channels (6 quadrants) of a certain type of fuze test, the fuze launch window on the bomb continuously emits laser pulses outward. The receiving system of the tested equipment receives light pulses and converts them into electrical pulses of a certain frequency. The test equipment receives the test command sent by the signal processing system through the serial interface, receives the electrical pulse converted by the detection system on the selected test channel, and after a delay control of a pulse cycle, the simulated target echo signal Send it to the corresponding launch system of the test equipment. That ...

Abstract

A fuse detection device based on pulse laser ranging principles mainly comprises a power supply, a laser, an optical emission system, an optical receiving system, a detector, a pulse amplifier, a signal processing and decision circuit, and the like. According to the fuse detection device, pulse laser fuse detection is adopted, the fuse detection device has confidentiality and anti-interference performance as the laser has good monochromaticity, the locating accuracy of fuse is largely increased as the laser has good directionality, and the sensitivity of the fuse is increased as the laser has high luminance, and therefore the fuse detection device has good anti-electromagnetic interference capability, working safety, reliability and high ranging accuracy, and is widely applied in the aviation field.

Description

technical field [0001] The invention belongs to the technical field of laser fuzes, and in particular relates to a fuze testing device based on the principle of pulsed laser distance measurement. Background technique [0002] A laser fuze is a detection device that is used by a missile or other weapon to detect whether the target enters the killing range of the weapon when it rendezvous with the target. Laser fuze has the characteristics of high positioning accuracy, high resolution and strong anti-electromagnetic interference ability. [0003] Chinese Patent Announcement CN201583211U (Patent No. 200920299191.0) discloses "a laser fuze". The utility model relates to a laser fuze, the purpose of which is to reduce the false alarm probability of the laser fuze. A laser fuze includes a transmitting optical system, a transmitting circuit, an information processing circuit, a receiving optical system, a receiving circuit, a laser and a detector, and is characterized in that it a...
