Paper Abstract

We present a novel passive radar imaging method for moving targets using distributed apertures. We develop a passive measurement model that relates measurements at a given receiver to measurements at other receivers. We formulate the passive imaging problem as a Generalized likelihood ratio test (GLRT) for a hypothetical target located at an unknown position, moving with an unknown velocity. We design a linear discriminant functional by maximizing the signal-to-noise ratio (SNR) of the test-statistic, and use the resulting position- and velocity-resolved test-statistic to form an image of the scene of interest. We present numerical experiments to demonstrate the performance of our imaging method.
