Time-Varying Electrostatic Modeling Techniques

Abstract

ARL developed computer models and modeling techniques based on the Method of Moments, and has used them for some time to study electrostatic fields associated with targets, terrain clutter, and sensors of interest. Recent extensions to these unique ARL capabilities allow some dynamic conditions to be modeled as a time series of quasi-static models. These new techniques have enabled us to study the extremely low-frequency (ELF) effects of rotating helicopter blades on both airborne and remote sensors. Examples show how a dynamic helicopter model can be used to compute time-varying airborne fieldmeter calibration factors for aircraft charge and atmospheric electric field measurements, and remote ELF electric fields which might be detected by passive surveillance sensors.
