A Method for Utilizing Commercially Available Sensors to Investigate Magnetic Field Perturbations Associated with Ballistic Events
Abstract
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.
