Ballistic Reentry Vehicle Aerodynamic Coefficient Estimation Using an Advanced System Identification Technique
Abstract
This report develops post-flight data processing methods for aerodynamic coefficient estimation of ballistic reentry vehicles based on advanced system identification technology. This post-flight data processing involves reconstruction of unmeasured channels, aerodynamic coefficient model structure determination and maximum likelihood parameter estimation. The methods are verified on a simulation trajectory and on a flight test trajectory. It is shown that the techniques are general enough to handle a variety of regimes encountered by a typical ballistic reentry vehicle.
