| 摘要: |
| 针对传统非合作目标定位方法对回波信号的群路径误差敏感和性能不稳定的缺陷，提出了距离信息遗传迭代算法来实现非合作目标的定位。详细介绍了距离信息的遗传迭代算法，并构建了一发三收的多基地探测系统，开展了以电离层不均匀体作为非合作目标的定位试验。通过试验，成功获得了非合作目标的经度、纬度和高度信息。研究表明：该方法具有自我反馈机制，能够避免定位结果陷入局部最优解和算法性能的不稳定，为非合作目标定位的研究提供了一种新的思路。 |

| Abstract: |
| For the drawback that the traditional location method of non-cooperative target is sensitive to the group path error of echo-signal and the performance is instable,the genetic iterative algorithm based on the distance information is presented in this paper to locate the non-cooperative target. The genetic iterative algorithm based on the distance information is introduced in detail. Furthermore,with the multi-base detection,the location experiment of the non-cooperative target which is the ionospheric irregularity is carried out. Through above experiment,the longitude,latitude and altitude of the non-cooperative target can be obtained. The study shows the location technology has feedback mechanism to avoid the location results into local optimal solution and instable performance,which provides a new idea for the study of non-cooperative target location. |
