Based on the configure of direction finding , the location method , algorithm , accuracy and performance for multistations and single station are studied in this thesis , and the computer simulation results are given out . it is important of resolving the performance of antenna array . a technique to estimate and calibrate the performance is developed in this page 本文以测向系统的组成为基础,研究了单平台情况下利用到达方向、到达时间差、多普勒频率差、相位变化率等参数的测向方法、测向算法、测向精度和性能,并进行了计算机仿真,为无源测向系统的设计和实施提供了重要的理论基础和实验数据。
