Abstract

The invention relates to the technical field of laser Fuze test, in particular to a target simulator. The target simulator comprises a mechanical skeleton, optical test passages assembled on the mechanical skeleton and a control circuit. The target simulator has four quadrants, and each of the quadrants has four optical test passages. Each optical test passage comprises an optical switching circuit printed board, as well as a light receiving collimator, a light switch and a light emission coupler which are all connected through an optical fiber. During use, the mechanical skeleton is bounded on a corresponding aircraft. The control circuit is used for controlling the on or the off of the light switches of the four quadrants and comprises a power supply module, a single chip microcomputer and a serial port conversion chip; and the power supply module, the single chip microcomputer and the serial port conversion chip are all arranged on the internal plate of the mechanical skeleton. The target simulator provided by the invention solves the problem in the prior art that the existing target simulators are poor in synchronous processing of system pulse signals and replaceability of parts by the application of the optical fibers.

Description

technical field [0001] The invention relates to the technical field of laser fuze testing, in particular to a target simulator. Background technique [0002] Target simulators are often used to simulate target motion or to simulate relative motion between aircraft and targets. When used on missiles, they play a key role in improving the accuracy of missiles hitting targets. At present, the target simulators available on the market are mainly realized by circuits, which are composed of power supply, laser, transmitting optical system, receiving optical system, detector and pulse amplifier, signal processor and decision circuit. The transmitting system emits a laser with a certain frequency and energy. The receiving system mainly completes the detection of the laser reflected back from the target. The judgment circuit is used to judge the target signal and give the detonation signal. The signal processing system completes the output pulse sampling and filtering; the echo pulse...
