Abstract
Unlike phased array, frequency diverse array (FDA) applies a tiny frequency offset across the antenna elements to generate a range-angle-dependent beampattern. However, due to the range-angle coupling property, the emitter position cannot be obtained directly from conventional FDA beamforming peaks. This paper proposes a novel passive localization approach based on direction modulation (DM) and Chan algorithm. By applying DM, the angle-range coupling can be wiped off well, which has a significant influence on the emitter localization. Simulation results are implemented to verify the validity and superiority of the proposed technique.Keywords
