摘要:

随着小型无人机威胁日益加剧,研发用于探测小型无人机的雷达已成为重要课题。在前期研究中,我们提出了驻点集中(SPC)技术,用于调频连续波(FMCW)雷达的小型无人机检测。SPC技术是一种抑制FMCW雷达固有问题——泄漏的新方法,它通过降低噪声基底提升小型无人机的信噪比,还能提供无人机的精确距离与速度信息。但SPC技术在实际实现中存在不足。本文明确阐述了SPC技术的缺陷,提出了高级SPC(A-SPC)技术。A-SPC技术既能保留SPC技术的全部优势,又能克服其缺陷。实验结果验证了所提A-SPC技术的有效性,展现了其鲁棒性与实用价值。

英文摘要:

As the threats of small drones have grown, developing radars to detect the small drones has become an important issue. In earlier studies, we proposed the stationary point concentration (SPC) technique for the small drone detection with frequency-modulated continuous-wave (FMCW) radar. The SPC technique is a new approach to mitigate the leakage that is an inherent problem in the FMCW radar. The SPC technique improves the signal-to-noise ratio of the small drones by reducing the noise floor and provides accurate distance and velocity information of the small drones. However, the SPC technique has shortcomings in realizing it. In this paper, we present the drawbacks of the SPC technique clearly and propose an advanced SPC (A-SPC) technique. The A-SPC technique can overcome the drawbacks of the SPC technique while taking all the good effects of the SPC technique. The experimental results verify the proposed A-SPC technique and show its robustness and usefulness.
