DEVELOPMENT OF ANTICIPATORY AUTOMOBILE CRASH SENSORS

A COMPREHENSIVE EXAMINATION IS CARRIED OUT TO DETERMINE THE BASIC SYSTEM CONSTRAINTS AND REQUIRED OPERATIONAL CHARACTERISTICS FOR ANTICIPATORY SENSING OF IMPENDING AUTOMOBILE CRASHES. THIS IS FOLLOWED BY CONSIDERATION OF A WIDE VARIETY OF POSSIBLE SENSING TECHNIQUES AND SELECTION OF THOSE DESERVING OF FURTHER STUDY. TWO METHODS ARE CHOSEN, MICROWAVE RADAR AND ULTRASONIC SONAR, AND THE ADVANTAGES, WEAKNESSES, AND UNCERTAIN AREAS OF BOTH ARE DELINEATED. REALIZATION OF BOTH SENSORS IS DESCRIBED. THE RADAR SENSOR, COMPRISING STANDARD MICROWAVE COMPONENTS AND SOLID STATE CIRCUITRY, WAS INSTALLED ON A TEST VEHICLE FOR CHARACTERIZATION. RESULTS ARE PROMISING, BUT PRELIMINARY. THE SONAR APPROACH IS A TRANSLATION OF THE RADAR SENSOR INTO ACOUSTIC FORM. /AUTHOR/
