摘　　要：本文在原有大时窗搜救生物雷达基础上,改进硬件电路设计,实现了对时窗的分段自由选择,同时进一步结合delphi多线程编程技术,通过无线网络采集雷达回波数据,对得到的回波进行信号处理给出时窗分段探测结果。新建立的搜救生物雷达分段时窗探测系统,能够控制实现任一分段时窗自由选择探测和分段时窗从前往后连续探测,该系统在探测准确性,时窗选择灵活性等方面均优于原有探测系统,可用于复杂环境的救援行动,能大幅提高灾后救援效率。Improved hardware circuit of life-rescue bio-radar was implemented in this paper to achieve the free selection of the segmented time-window.Then the multi-threaded programming techniques were employed to collect the radar echo data through a wireless network.Simultaneously,the signal processing result was revealed on a laptop terminal.The newly established segmented time-window liferescue bio-radar detection system was capable of freely choosing the segmented time-window to carry out a detecting procedure and detecting in a continuous order from front to back in the detection region.The system was superior in terms of detection accuracy and flexibility when compared with the original detection system,and it could be used for rescue operations in complex environments,which greatly improved the efficiency of disaster relief.
