Abstract
The invention relates to a practical test method of code recognition ability of a laser alarm which can examine the actual code recognition ability of the laser alarm, and belongs to the technical field of the photoelectric detection instrument. Simulative test method in prior art is limited in that the test result cannot reflect the code recognition ability of the laser alarm in a real working environment. The method of the invention is characterized in that a pulse position code is compiled and inputted to a coder, wherein the coder outputs an electric pulse signal with the frequency and sequence changing according to the pulse position code in form of TTL (Transistor-Transistor Logic) level drive. The electric pulse signal modulates a laser power supply which generates a high voltage drive pulse as a pumping source energy of the laser. The laser outputs the pulse laser of the pulse position code carried on frequency and sequence. The pulse laser emits light toward the laser alarm to be tested. The laser alarm receives the pulse laser and compares the pulse laser with pre-stored own and friend pulse lasers in terms of pulse position code so as to complete identification and alarming.
Description
Technical field
The present invention relates to a kind of laser warning machine code identification ability method of testing under battle conditions, can examine the actual coding recognition capability of laser warning machine, belong to Photoelectric Detection instrument technical field.
Background technology
Defence object enemy range finder using laser, laser target designator and laser radar etc. that the laser warning eedle is right, identification through one's own side, the friendly side's arteries and veins bit code that comparison prestores, are made identification and alarm from the arteries and veins bit code of the not clear laser of these devices.Therefore, the laser warning machine must have the reliable coding recognition capability, when the laser warning machine dispatches from the factory and after using a period of time, and must its code identification ability of test.The method of testing of existing laser warning machine code identification ability is a simulating experimental, owing to belong to emulation mode, therefore, this method has limitation, and test result can not be reacted the code identification ability of laser warning machine under the real work environment.
Summary of the invention
The objective of the invention is to, with the code identification ability of under battle conditions mode testing laser alarm machine, grasp the true code identification ability of laser warning machine, for this reason, we have invented a kind of laser warning machine code identification ability method of testing under battle conditions.
The present invention's laser warning machine code identification ability method of testing under battle conditions is characterized in that, establishment arteries and veins bit code, and the input coding device, scrambler is with Transistor-Transistor Logic level drive form output frequency, the sequence electric impulse signal by the institute's arteries and veins bit code of being compiled variation; This electric impulse signal modulated laser power supply, Laser Power Devices produce the high drive pulse as the laser pump source energy, and the pulse laser of the arteries and veins bit code of compiling is carried in laser instrument output on frequency, sequence; This pulse laser carries out arteries and veins bit code comparison with the one's own side, the friendly square pulse laser that prestore according to being tried the laser warning machine behind this pulse laser of laser warning machine reception, accomplishes and discerns and alarm.
Its technique effect of the present invention is; The pulse laser that is received by examination laser warning machine is identical with the pulse laser of true threaten laser such as emissions such as enemy's range finder using laser, laser target designator and laser radar; During the laser warning machine is equivalent to be under battle conditions in test; The laser warning function is accurately identification and correct alarm not, directly reflects the code identification ability of laser warning machine.No matter need the frequency of pulse laser, sequence how to change, all can realize that have diversity and flexibility characteristics, therefore, the present invention's method can satisfy the test request of laser warning machine code identification ability fully through coding.
Embodiment
The present invention's laser warning machine code identification ability its embodiment of method of testing under battle conditions is following.Establishment arteries and veins bit code, the input coding device, scrambler is with Transistor-Transistor Logic level drive form output frequency, the sequence electric impulse signal by the institute's arteries and veins bit code of being compiled variation.Said scrambler adopts high speed electronics to make, and the electric impulse signal of output becomes a kind of high resolving power, high precision, wide region and 2～8 s' coded pulse trigger pip.This electric impulse signal modulated laser power supply, Laser Power Devices produce the high drive pulse as the laser pump source energy, and the pulse laser of the arteries and veins bit code of compiling is carried in laser instrument output on frequency, sequence.Said laser instrument is a repetition frequency near infrared solid pulse code laser instrument, adopts the codope laser crystal as working-laser material, can cross repetition steady operation in the outdoor temperature scope, and the pulse laser of output has higher monopulse output energy.This pulse laser carries out arteries and veins bit code comparison with the one's own side, the friendly square pulse laser that prestore according to being tried the laser warning machine behind this pulse laser of laser warning machine reception, accomplishes and discerns and alarm.
