摘 要：New geolocation methods are needed that will allow accurate location of LPI emitters despite low signal-to-noise ratio (SNR) and multipath propagation. To address this recent work has provided a single-stage localization method called Direct Position Determination (DPD). However, all its computation is concentrated at one computing node. We developed several methods to remedy this problem. To provide even better performance in these challenging real-world scenarios we developed a one-stage TDOA/FDOA localization method based on spatial sparsity of emitters. The proposed sparsity-based method has better performance (especially in multi-path and multi-emitter cases) compared to direct position determination (DPD) and two- stage Classic localization methods.
