Military Automatic Target Scoring System(MATSS) Based On The Technology Of Ultrasonic Exploration

The technology of ultrasonic exploration are the technology used in processing, analyzing and comprehending the ultrasonic information by right of computer. Along with the immense progress in the science and technology of computer, the technology of ultrasonic exploration are extending the applicable field of it. And the technology of ultrasonic exploration have unprecedented of applied value and applicability. Now, the Military Automatic Target Scoring System(MATSS) based on the technology of ultrasonic exploration, as a kind of new target scoring technology, begin to be applied in the project of military shooting training and competition. The thesis take actual circumstance of the enterprise of small arms as research object. Make use of ultrasonic sensors to collect ultrasonic information, and make use of AT89C52 to collect the time difference between all of the ultrasonic sensors. Then send the time difference information to the computer through the RS-485 Bus. And get the bullet locality on the target sheet through the calculator processing, then computing various gunning of a weapons weapon to experiment the parameter.This thesis introduces the basic constitute and the function of the system first, carried out the total solution programming to the whole system. Combining the technique of the aerodynamicist studies the characteristic of the wave which the supersonic speed bullet results in, then studied the mechanism of the sonic boom and the characteristic of the sensor. Then analyzed the key problem of the system , establish mathematics model which based on the analyse , this model was more vivid in spreading and arranging the sensors, So it obtain the bullet position more easy and responded more quickly. Finally, according to the analytical research of the signal frequency chart characteristic of shock wave obtain the guidelines of the sensor, at last completed the electric circuit design of the MATSS.
