摘要
针对航迹融合算法的性能分析,一般只考虑融合误差而无法全面评价融合算法的问题,提出了一种基于计算量的航迹融合算法性能分析方法。该方法通过采用以浮点操作数为单位的方法统计算法主要步骤的计算量进行计算量理论分析,通过计算机仿真进行误差仿真分析,最后通过综合评估模型实现对融合算法的全面评价。仿真实验结果表明,算法运行时间比值在一定误差范围内验证了计算量理论分析的正确性,新的性能分析方法可以有效地评价融合算法性能,为融合算法的性能分析提供参考。
For the problem that the performance analysis of the track fusion algorithm only considered the fusion error,and the fusion algorithm could not be comprehensively evaluated,A performance analysis method of track fusion algorithm based on calculation was proposed,which was based on the computational quantity theory analysis and the position error simulation analysis to the performance of the algorithm.The method performed theoretical analysis of the calculation amount by using the calculation amount of the main steps of the statistical algorithm in the method of floating-point operands,and the error simulation was analyzed by computer simulation.Finally,the comprehensive evaluation model was used to realize the comprehensive evaluation of the fusion algorithm.The results of the simulation experiment showed that the correctness of the theoretical analysis of the computational quantity was verified by the algorithm running time ratio within a certain error range,and the new performance analysis method could effectively evaluate the performance of the fusion algorithm,which provided a reference for the performance analysis of the fusion algorithm.
