查询词典 echo-location

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

该文根据地海杂波与流星干扰在多普勒谱上的差别，提出了用FIR型高通滤波器滤除杂波使流星干扰凸显出来；再根据流星干扰的分布特点分段计算背景噪声均值，求取流星干扰检测门限；最后用杂波信号来插值流星干扰位置上的数据，消除因去除干扰造成的杂波相位不连续。
