Subsurface Electromagnetic Target Characterization and Identification

Abstract

A method for subsurface radar target characterization and identification is described. This method characterizes subsurface radar targets by their complex natural resonances which are extracted directly from their backscattered timedomain waveforms. The difference equation coefficients associated with the complex resonances are then used in the predictor-correlator for target identification. Both the characterization and identification processes are extensively tested with real radar measurements and found to yield practical target identification performance. The target identification process is simple and involves only simple algebraic operations. Based on the identification process, a first-generation microcomputer identification radar system is implemented for target identification in real time. This radar system is found to yield practical identification performance.
