中文摘要:
      主要研究了INS/SAR组合对运动目标的定位算法。首先,建立了INS/SAR组合定位系统数学模型;其次,基于卡尔曼滤波方法和alpha-beta滤波方法完成了INS/SAR组合定位算法设计;最后,考虑组合导航系统误差及导引头测量误差,对定位算法进行了数字仿真及性能分析。仿真结果表明,所设计的INS/SAR组合定位算法在远距对运动目标具有较高的定位精度。
English Summary:
      This paper mainly studies the INS/SAR combination for the moving target positioning algorithm. Firstly, established the mathematical model of INS/SAR integrated positioning system; secondly, completed the design of INS/SAR integrated positioning algorithm based on Kalman filtering method and alpha-beta filtering method; finally, considering error in the integrated navigation system and the measurement error of the seeker, conduct the digital simulation and performance analysis for the location algorithm. The simulation results indicate that, the designed INS/SAR integrated positioning algorithm has high moving target locating and speed accuracy to the moving target in the distance.
