A Single-Node Aerial Target Location Method Based on Satellite Radiation Source

In practical applications, the target observation space is often covered by only a single receiving station. Thus, it is necessary to explore a novel target localization method under single receiving station condition. In this paper, a single-node aerial target location method based on satellite radiation source is presented. Firstly, utilizing the spatial geometric relationship between the aerial space configuration in dual station and the target, established the measurement model including bistatic range-delay, pitching AOA and azimuth AOA. Then, the receiving range can be estimated using digital beamforming technology based on the receiving array antenna, where the antenna beam coverage information and the prior target altitude information are combined. Finaly, the three dimensional target localization is skilfuly derived according to the bistatic configuration, and thus to avoid the parameter unrecognizable problem caused by insufficient degrees of freedom. The proposed algorithm fully exploits the intrinsic corelation characteristics between the measurement information and the bistatic configuation, which provides an effective way for aerial target localization. Simulation results verify the effectiveness of the proposed algorithm.
