In this paper, a TDOA location algorithm proposed by Chan is improved, and a TOA/AOA hybrid location algorithm which inherits the advantages of original algorithm and provides an enhanced performance by making use of the AOA measurement is proposed.

• 为此,本文对Chan提出的电波到达时间差(TDOA)定位算法进行了改进,提出了一种既继承原算法的优点,又增加AOA测量值以提高定位性能的TOA/AOA混合定位算法。
