The millimetre wave (MMW) seeker can realize target detection under all weather conditions, the performance of which directly determines the design of the control algorithms. To guarantee the hitting accuracy and damaging effect of the expensive MMW guidance missile, assessing the performance of the seeker is indispensable before the launching of the missile. Real tactical environment of the seeker cannot be simulated comprehensively by indoor laboratories, and high-precision evaluation method outdoor is desperately needed. Focusing on the problem, a method for outdoor MMW seeker performance evaluation is proposed via the real-time kinematic (RTK) technology in this paper, which has the advantages of high-precision orientation and working ability under all climates. Firstly, the geometry of the seeker performance evaluation system is constructed, guaranteeing the effective working of the RTK. And then, the key parameters associated with the guidance control are calculated on the basis of the global position system (GPS) measurements. Finally, comparisons are made between the parameters obtained based on the RTK and the seeker outputs. Besides, for the performance assessment of the MMW seeker towards moving targets, a time synchronization method for different GPS carrier platforms is presented. The effectiveness of the proposed method is validated by the mooring test-fly experiments. Experimental results demonstrate that the performance of the MMW seeker can be evaluated effectively by using the proposed RTK-based method.

基于实时运动学的毫米波搜索器性能评估

毫米波(MMW)搜寻器可以在所有天气条件下实现目标检测,其性能直接决定了控制算法的设计。为了保证昂贵的MMW制导导弹的命中精度和破坏效果,在发射导弹之前必须评估导引头的性能。室内实验室无法对模拟者的真实战术环境进行全面模拟,因此迫切需要一种高精度的户外评估方法。针对这一问题,本文提出了一种通过实时运动学(RTK)技术进行户外MMW导引头性能评估的方法,该方法具有高精度定位和在所有气候条件下都能工作的优点。首先,构建搜寻器性能评估系统的几何结构,保证RTK的有效运行。然后,基于全球定位系统(GPS)测量来计算与制导控制相关的关键参数。最后,在基于RTK的参数与搜索器输出之间进行比较。此外,为了评估毫米波导引头对移动目标的性能,提出了一种针对不同GPS载体平台的时间同步方法。通过系泊试飞实验验证了该方法的有效性。实验结果表明,使用建议的基于RTK的方法可以有效地评估MMW搜寻器的性能。根据全球定位系统(GPS)的测量结果计算与制导控制相关的关键参数。最后,在基于RTK的参数与搜索器输出之间进行比较。此外,为了评估毫米波导引头对移动目标的性能,提出了一种针对不同GPS载体平台的时间同步方法。通过系泊试飞实验验证了该方法的有效性。实验结果表明,使用建议的基于RTK的方法可以有效地评估MMW搜寻器的性能。根据全球定位系统(GPS)的测量结果计算与制导控制相关的关键参数。最后,在基于RTK的参数与搜索器输出之间进行比较。此外,为了评估毫米波导引头对移动目标的性能,提出了一种针对不同GPS载体平台的时间同步方法。通过系泊试飞实验验证了该方法的有效性。实验结果表明,使用建议的基于RTK的方法可以有效地评估MMW搜寻器的性能。提出了一种针对不同GPS载体平台的时间同步方法。通过系泊试飞实验验证了该方法的有效性。实验结果表明,使用建议的基于RTK的方法可以有效地评估MMW搜寻器的性能。提出了一种针对不同GPS载体平台的时间同步方法。通过系泊试飞实验验证了该方法的有效性。实验结果表明,使用建议的基于RTK的方法可以有效地评估MMW搜寻器的性能。
