Paper Abstract

In this article, we present a method for estimating the translational motion parameters of a target from its ISAR signature. The method exploits the phase of the target's frequency response and does not require 2D Fourier processing. The basis for this method is a phase difference indicator which converges to an absolute minimum when the phase is compensated with the true values of the motion parameters. The analysis of the phase difference indicator leads to an algorithm for motion parameter optimization. Processing of simulated and experimental ISAR signatures demonstrates that the phase difference method is extremely computationally efficient and equally accurate when compared to robust techniques based on entropy or Fisher information indicators.
