N2 - In this paper, we present a novel method for passive imaging of stationary targets using phaseless measurements. One of the main benefits of the proposed approach is increased robustness to uncertainties inherent in passive imaging. Furthermore, unlike most passive radar imaging methods, our approach circumvents the need for two receivers by auto-correlating the received bistatic signal. Since the resulting measurements are phaseless, coherent imaging algorithms previously used in radar are no longer applicable. Thus, we propose an optimization based approach using the Wirtinger Flow algorithm. This is a non-convex approach, offering computational efficiency not realizable by convex alternatives. Through numerical simulations we demonstrate the effectiveness of this approach.
