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.
