| Abstract: |
| Due to the design weakness of the delay line of anolog Surface Acousti
c Wave Filter（SAWF） in analog pulse transponder,a digita
l time delay compensation method with high precision is proposed based on digita
l store and forward(SAF) tec
hnique of FPGA, which improves time delay transmitting precision of the transpon
der. The pulse transponder has such merits as easily modified time delay,
high transmitting precision. This method is of great benefit to some p
rojects. |
