1) carrier-wave extending
载波扩展
1.
At the same time,for the possible extreme points,a precise search process based on the carrier-wave extending is taken.

2) extended filtering
扩展滤波
3) spread clutter
扩展杂波
1.
There is dominated spread clutter derived from the range-folded echoes in particular range bins,and targets located at that region would be submerged,that is a blind region for detection.
该距离多跳回波在某些特定的距离单元呈现较强的扩展杂波,淹没位于该区域的目标信号,形成检测盲区。
2.
However, due to the complex propagation conditions of electromagnetic wave in HF band, many disadvantageous factors, such as phase path contamination and multimode propagation, will cause the neighboring target submerged in the spread clutter.
通过实验仿真说明 ,改进后的方法能够有效地改善扩展杂波的抑制效
