Abstract
Generating accurate, high‐resolution time‐frequency distributions (TFD) is a critical aspect of dynamic radar scattering analysis. Well‐formed TFD's can be used for target identification, target acquisition in high‐noise environments, or extending the range of radar systems. In this paper, we diverge from traditional methods employing complex signal‐processing methods and propose a simple approach for constructing the TFD for computational electromagnetic (CEM) targets based on the physics of the problem. The proposed method allows for an arbitrarily high resolution at any single look angle. Several examples are presented to validate the method. © 2002 Wiley Periodicals, Inc.
