back-scattering

In this paper the envelope shape of bottom back-scattering signal received by swath,using direchonal transmitting and receiving, is analysed.

文中分析了在方向性发射和接收情况下，条带测深仪接收海底反向散射信号的包络波形。

The approach uses the parasitic inductance of the antenna to implement ASK modulation by adjusting the capacitive reactance of the matching network,which changes with the backscatter circuit.

该阻抗匹配方法利用天线的寄生电感,通过调整反向散射电路的电容来改变匹配网络的容抗,从而实现ASK调制。
