| 摘要: |
| 对辐射源进行无源定位是电子战领域的一个重要问题。针对短基线时差定位技术对时差测量精度要求很高的难题，提出了一种基于相位差的修正伪线性最小二乘算法。相较于非线性最小二乘法(NLS)，修正伪线性最小二乘法的优势是可以得到目标位置表达式，不需要迭代运算，计算效率较高；不需要定位初值，避免了算法发散问题。理论分析和仿真均说明修正伪线性最小二乘法可用于短基线情况下的目标定位。 |

| Abstract: |
| Passive location of radiation source is an important issue in the field of electronic warfare.Because the requirement of time-difference precision is hard,a modified pseudo linear least square algorithm based on phase difference is presented in the case of short baseline.The new method can acquire the target′s location expression,and requires no iterative operation,so it has high computation efficiency.It doesn′t need initial position and avoids divergence problem of algorithm.The new method can be used to locate target in the case of short baseline by theory analysis and simulation. |
| Key words: passive location pseudo linear weight nonlinear least squares phase difference |
