| 摘 要： | 在CDMA的网络环境下,TDOA/AOA混合定位算法能够比Chan算法有较高的定位精度。然而随着AOA测量误差精度的下降,定位精度逐渐下降,甚至低于Chan算法的定位精度。提出了一种既能继承原算法的优良性能,又可充分利用AOA测量值信息提高定位性能的TDOA/AOA混合定位算法。实验证明,该方法的定位误差性能优于单纯的TDOA定位方法。

| Abstract: | The hybrid algorithm of TDOA/AOA has better location accuracy than Chan algorithm under the CDMAnetwork,butwith the fall ofAOAps accuracy,the location accuracywill drop gradually,andmay below the Chanps. In this paper,a time difference of arrival (TDOA) location algorithm is extended to a TDOA/ AOA hybrid location algo2rithm which can not only inherit the good performance of the original algorithm ,but also improve the location accuracy by making full use of the AOA measurement. Simulations showed that the ... |
