摘　　要：毫米波导引头可穿透云、雨、烟、雾,实现目标的全天候探测,其性能指标直接决定了控制算法的设计。为保证造价昂贵的毫米波制导武器系统的命中精度和毁伤效果,需要对毫米波导引头的性能进行准确的评估。然而仅仅通过实验室测试无法模拟真实的作战使用环境,需要高精度的外场测试方法准确评估导引头性能。针对此问题,提出了一种基于RTK的毫米波导引头性能评估方法。首先,基于GPS的测量结果实时计算导引头参数;然后,将计算结果与导引头自身的输出进行对比分析;最后,评估毫米波导引头各性能指标的精度。实测数据验证了所提方法的有效性。The millimeter wave (MMW) seeker has the capability of penetrating the cloud, rain, smoke and frog, realizing target detection under all weather conditions. Its performance directly determines the design of the control algorithms. To guarantee the hitting precision and destruction effect, assessing the performance of the seeker will be beneficial and indispensable. Real tactical environment cannot be simulated by indoor laboratory, so that high-precision evaluation method outdoors is desperately needed to assess the performance of the seeker. Focusing on the problem, an outdoor assessment method of seeker performance based on real-time kinematic (RTK) technology is presented. Firstly, the parameters of the seeker are calculated based on the real data collected by differential global position system (GPS). And then, comparisons are made between the ones obtained based on RTK and the seeker outputs. Finally, assessments are given to evaluate the performance of the MMW seeker. Real MMW data verifies the effectiveness of the proposed method.
