摘要
火炮导弹等武器的精度越来越高,而与之相匹配的武器测试评估与训练系统明显滞后。针对传统的四元阵、五元阵定位精度较低,采用单基阵精确定向多基阵融合定位的原理,将小孔径基阵与无线传感网络技术结合,提出一种全天候、多环境适应性、实时性强的炮弹落炸点测量系统。介绍基于小孔径的单基阵定向部分,提出一种改进的立体五元阵,给出优化的定向算法和时延估计方法,详细分析定向误差。户外进行定位实验验证系统性能,实验结果表明,系统单基阵定向方位角小于0.52°,俯仰角小于1.33°,定向性能较好;多基阵对X、Y坐标的定位精度优于0.8 m,对Z坐标的定位精度优于1.5 m,定位精度满足工程需要。
While precision of artillery,missiles and other weapons wasgetting higher,testing and training system which was matched hadlagged far behind. Againsted the low locationprecision of traditional four-element and five-element array,usedsingle-array to measure direction and multi-array to measure position. Combined small-aperture array withwireless sensor network technology,and put forward anall-weather,multi-environment adapting and real-time near-ground bombing point measure system. Introduced the direction system based on small-aperture array,and put forward an improved tridimensional five-element array. Given the optimized direction algorithm and time-delay estimating method,and analyzed the deviation in detail. Conducted several experiments outdoors. The results indicated that the azimuth angle was less than 0. 52° and the pitching angle was less than 1. 33°. In addition,the systemperformed well that the precision of X and Y coordinates was better than 0. 8 m,and Z coordinate better than 1. 5 m. Localization precision met the demand of engineering.
