| 摘 要： | 本文在三基地雷达二维定位最佳算法的基础上,充分利用各站测量信息,在不增加设备的前提下,推导出三基地雷达三维空间的最佳定位算法,并加以仿真。结果显示,在均匀布站和直线布站两种方式下,空间相关数据压缩算法比独立数据压缩算法更加有效地提高了目标定位精度,特别是较好地改善了发射站附近区域的定位性能,有效解决了双基地雷达空间定位的基线盲区问题。直线布站定位性能略优于均匀布站,三基地定位性能明显优于双基地定位性能。

| Abstract: | Based on 3-radar 2D optimum location algorithm,this paper presents space 3-radar optimum location algorithm by making full use of measure information of all stations,without adding any equipment.Our simulation results show that the space correlated data compression algorithm can increase the location accuracy much effectively than the independent data compression algorithm under both linear and symmetrical distributions.Moreover,it can especially improve the location capability near the transmitter station,and the location blind areas of the 2-radar space location near the base line can also be decreased.Linear distribution is slightly superior to symmetrical distribution,and 3-radar system is more accurate than 2-radar system. |
