摘要

This report presents an architectural framework for utilizing commercially available magnetic sensors to investigate magnetic field perturbations associated with ballistic events. Specifically, the Honeywell HMC1043 three-axis magnetoresistive field sensor is considered along with required circuitry to provide signal offset compensation, signal amplification, and set/reset strap capability. Conditions are quantified for which active offset compensation is desirable, and a method for achieving this compensation is discussed along with the constraints that active compensation imposes on signal amplification. A method for realizing optimal magnetic sensor performance through sensor conditioning set/reset operations is presented. A scheme for integrating an array of 32 HMC1043 magnetic field sensors into a microprocessor-controlled data acquisition and storage system is outlined, and fabrication details are provided.
