In order to remove the trace-interval horizontal disturbance, on the basis of studying digital filtering this paper presents a kind of horizontal prediction filtration algorithm which combines the IIR filter and predictive algorithm. By setting up predictive step length, achieving the coefficient between predictive and actual value using predictive deconvolution and designing the IIR high pass filter according to the coefficient, this algorithm realizes a highly accurate and adjustable denoising method. The application to GPR signal demonstrates that this algorithm can effectively remove horizontal disturbance and select useful information.
