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。

Results 12 cases as abdominal hernia (of which indirect hernia 9 cases, direct hernia 2 cases, femorocele 1 case), ultrasonography shows middle-high echo or linkage heterogeniety echo clumps; 8 cases as hydrocele, Ultrasonogram shows anechoic; 2 cases as cryptorchidism, ultrasonography shows normal testicular middle-echo; 4 cases as lymph node mass (of which lymphoma 2 cases, lymph node metastasis 1 case, lymph node inflammatory change 1 case), acoustic image shows low weak echo; 4 cases as substance mass (of which fibroma 1 case, spermatic cord tumor 1 case, Desmoid tumor 1 case, spermatic cord inflammation 1 case), Ultrasonography shows non-uniformity middle-highor low echo.
