  1. Based on the analysis of the beat frequency signal, the expression of the beat frequency phase is deduced. the expression indicates physics meanings of quantities to be detected and supplies theoretical bases for detection methods. by using two - dimensional fft, the range and velocity information of target is got out from the echo. according to the periodicity range ambiguity of symmetrical pulses in fmpcw, the processing method of sliding time window is used

    通過對差頻信號進行的分析,得出了差頻相位的具體表達式,表現出了要檢測的各量的物理意義,對檢測的方法提供了理論依據。利用二維fft方法,可以有效地提取回波中目標的距離與速度信息。對于fmpcw信號由於均勻脈沖產生的周期性距離模糊的問題,採取時間波門的處理方法。
  2. A device used underwater to produce pulses of sound, as for an echo sounder

    聲脈沖發送器置於水下產生聲脈沖的裝置,如迴音器中的裝置
  3. In order to improve the ranging accuracy of a lidar, the effect of amplitude and width of the echo signal on the ranging accuracy of a lidar with bell - type laser pulses in temporal domain and gaussian pulses in spatial domain, was studied under the condition of constant - voltage - amplitude discrimination

    摘要為了提高脈沖激光雷達的測距精度,研究了光束在空域為高斯光束、時域為鐘型脈沖的激光雷達在恆電壓幅度鑒別模式下,回波信號幅度變化和寬度變化對測距精度的影響。
