MA-Enabled Integrated Radar and Jamming

Abstract

Fixed-position antenna (FPA) arrays provide limited spatial degrees of freedom for integrated radar and jamming (IRAJ), especially in multi-target scenarios. In this letter, we study a movable-antenna (MA)-enabled multi-target IRAJ system, where the transmit waveform and antenna positions are jointly optimized for deceptive jamming under sensing signal-to-interference-plus-noise ratio constraints. The resulting problem is highly nonconvex due to the coupling between waveform synthesis and array reconfiguration. To solve it, a block successive convex approximation-based alternating optimization algorithm is developed. Numerical results show that the proposed MA-enabled design outperforms the conventional FPA benchmark while satisfying the sensing constraints.
