| Ground penetrating radar (GPR) is an effective and non-destructive testing equipment. The radar transmits ultra wide band electromagnetic signal to the ground, and then receive the backscatter signal of the target through the antenna system. We can use the radar to detect, position and even get the three dimension images of the targets after the processing of the transmitted and received signals.Due to the development of the ground penetrating radar technology today, the requirement of the usable range is wider and wider. It means that we should devote more enthusiasm and energy to develop the antenna system.To solve the above problem, the adaptive antenna is to be used in the ground penetrating radar. We can get the optimum results with the use of the adaptive antenna.The main achievements and conclusions of this paper are summarized below:① Consult the reference about GPR and get the development information of the antenna used in GPR;② Summarize the design and analysis notes of the antenna used in ground penetrating radar, then some advices are given to avoid the influence of the ground type, and then the importance of the impedance loading technology and the shielding technology is discussed;③ Study the theory of the finite integration technique, include the Maxwell grid equations, the simulation excitation, the leap-frog scheme, numerical stability and the boundary condition;④ Based on the wire bow-tie antenna, the strip bow-tie antenna is simulated with the finite integration technique. The results of the simulation indicates that the strip bow-tie antenna can achieve the adaptive ability;⑤ Based on the results of the simulation, the control algorithm of the strip bow-tie antenna is discussed. |
