Analysis of Influencing Factors of Winter Bamboo Shoot Detection Based on GprMax forward Simulation
Winter bamboo shoot is one of the main sources of income of bamboo forest management,which contains rich nutri-ents and can bring good economic income to bamboo farmers.Through the establishment of Peplinski simulated soil model,GprMax forward simulation method was used to analyze the effects of buried depth and size of winter bamboo shoots on the echo images of GPR.The detection effect of winter bamboo shoots,stones and bamboo whips at the center frequency of 0.9GHz antenna was compared through underground winter bamboo shoots simulation test,and the field detection of winter bamboo shoots was car-ried out.The results show that the echo image of winter bamboo shoots is a typical hyperbola,and its shape is mainly determined by the buried depth of winter bamboo shoots and the difference of dielectric constant between the detected material and the soil.Due to the small number of data samples collected by ground penetrating radar,it is difficult to collect data.The GprMax simula-tion image obtained by setting different parameters such as the size and depth of winter bamboo shoots and combining with the echo image measured by ground penetrating radar to analyze the influencing factors of the detection effect of winter bamboo shoots can provide certain data support for the subsequent image classification of ground penetrating radar.
