We proposed the means of near field measurement correction and far - near - field fuzzy distinguish synthesis according to if fixed evaluation points exist . the method advanced in precision 针对有无固定评价点两种情况提出了近场测量修正法、远近场综合模糊识别法，使声源识别的精度明显提高。
2.
The algorithm only needs to solve an ill - posed linear system and a well - posed minimization problem and requires only the knowledge of the near field measurements of the scattered fields due to point source fields at a finite number of incidence and observation points distributed over a limited aperture 该算法只需求解一个不适定的线性系和一个适定的非线性最小化问题，而且只需要点源入射场的散射场在某个有限孔径中若干有限个入射和测量点上的近场测量信息。
