Electromagnetic test-facility characterization: An identification approach
Abstract
The response of an object subjected to high energy, transient electromagnetic (EM) fields sometimes called electromagnetic pulses (EMP), is an important issue in the survivability of electronic systems (e.g., aircraft), especially when the field is generated by a high altitude nuclear burst. The characterization of transient response information is a matter of national concern. Techniques to: (1) improve signal processing at a test facility; and (2) parameterize a particular object response are discussed. The application of identification based signal processing techniques to improve signal levels is considered. Models of test equipment are identified and used to deconvolve the input/output sequences for the object under test. A parametric model of the object is identified from this data. The model can be used to extrapolate the response to these threat level EMP. Also discussed is the development of a facility simulator (EMSIM) useful for experimental design and calibration and a deconvolution algorithm (DECONV) useful for removing probe effects from the measured data.
