Improved validation of ier results

摘要

Image editing and Reconstruction (IER) is used to estimate the RCS of component parts of a complex target. We discuss the general areas of controversy that surround the technique, and present of set of practical data procesing procedures for assiting in validation of the process. First, we illustrate a simple technique for validating the end-to-end signal processing chain. Second, we present a procedure that compares the original unedited, but fully calibrated, RCS data with the summation of all IER components. For example, if we segregate the image into two components-component of interest, remainder of the target mounting structure plus other clutter-we require that the two patterns coherently sum to the original. This indirectly refences the results to the calibration device. In addition, it provides a quantitative means of assessig the relative contribution of the component parts to overall RCS. We demonstrate the procedures using simulated and actual data.
