Abstract

Aiming at ranging precision of conventional photoelectric encoder is restricted by different scenarios

propose a FPGA platform design scheme for ground penetrating radar

ranging precision can be flexibly controlled

to complete signal acquisition

direction identification frequency division

counting

latching

transmission and other functions by FPGA platform and gives results in ground penetrating radar（ GPR） applications

the measured data show that accurate pulse counting and distance displaying can be realized.
