Method of single satellite passive geolocation using spatial sparsity
Traditional single satellite geolocation is divided into two separate phases：parameter estimation and target positioning，which causes non-optimal localization. To address this issue，a method of single satellite passive geolocation using spatial sparsity was presented. After continuously measuring th...

| description | Traditional single satellite geolocation is divided into two separate phases：parameter estimation and target positioning，which causes non-optimal localization. To address this issue，a method of single satellite passive geolocation using spatial sparsity was presented. After continuously measuring the Doppler frequency of the target signal and using the sparse distribution of the interference on the ground，a convex problem achieving geolocation through establishing the relation between Doppler frequency and target position of the interfering signal was introduced. The method leveraged cumulative time and spatial distribution of the interference and geolocation was completed in one phase. The simulations confirm that the proposed method can get high accuracy in single satellite geolocation. |
