AEROBALLISTIC DATA ACQUISITION SYSTEM (ADACS)

Q-DOT PROPOSES TO DEVELOP A COMPREHENSIVE AEROBALLISTIC DATA ACQUISITION SYSTEM (ADACS) TO REPLACE SPIN BOXES OR YAW CARDS ON THE BALLISTIC TEST RANGE. THE FULLY AUTOMATIC ADACS WILL ELIMINATE LABOR-INTENSIVE AND TIME-CONSUMING STEPS BETWEEN SHOTS WHILE IMPROVING ACCURACY OVER CURRENT METHODS. IN ADDITION TO SPIN DATA, ATTITUDE, AND VELOCITY DATA ARE ACQUIRED BY THE SAME EQUIPMENT. THE HEART OF THE PROPOSED ADACS IS A UNIQUE, HIGH-SPEED LINE IMAGER. EACH LINE COMPRISES UP TO 1024 PIXELS. THE IMAGER HAS ON-CHIP STORAGE FOR UP TO 512 LINES OF DATA. IT CAN ACQUIRE LINES AT RATES UP TO 1,000,000 LINES/SECOND. THE IMAGER IS SELF-TRIGGERING: IT DETECTS THE INTRUSION OF A PROJECTILE INTO THE SCENE AND COMMENCES DATA STORAGE, INCLUDING SEVERAL LINES BEFORE THE TRIGGERING EVENT. WITH ON-SITE, POSTACQUISITION SIGNAL PROCESSING, SPIN CAN BE RESOLVED TO 0.1% FROM 10 TO 250 RPS, ATTITUDE TO 0.1 DEG TO 10 DEG, AND VELOCITY TO 0.1% FROM 50 TO 2,220 M/SEC.
