| Abstract: |
| In the current design methods of direction finding(DF) array baselines in engineering projects,there exist problems such as time-consuming and labor-intensive,heavy reliance on the DF experience of technicians,and difficulty in designing complex DF arrays.For these problems,this paper proposes a technology for automatic generation of DF array baselines using deep reinforcement learning(DRL) method.Based on the related interferometer DF mechanism,the DRL method is adopted to design the DF array agent,focusing on breakthroughs in key technologies such as multi-scenario and multi-entity simulation modeling,array agent construction,and DF effectiveness evaluation.By using reinforcement learning repeated trial and error mechanism,iterative optimization is performed to obtain the optimal DF array that meets the index,thus greatly improving the array efficiency and DF quality,and the effectiveness of the proposed method is proved through experiments.The array baseline designed by this technology has been verified by DF test in projects,and its specifications meet the requirements of practical engineering applications. |
