Abstract: The high⁃frequency ground penetrating radar includes the 1.6 GHz radar antenna, radar host and wireless terminal. The wireless terminal is connected with radar host through 2.4 GHz UHF WiFi, and can display the inspection results. The self⁃defined data transmission protocol is used to control the state of radar host, adjust the signal gain and time window. On the basis of high⁃frequency ground penetrating radar, a security inspection software system based on Android is developed to detect the dangerous metal products. The difference of the detection results is studied under different distance conditions by means of the experimental tests of non⁃metallic target and metal target. The results demonstrated that, with the same detection distance, the reflected signal of the metal target is stronger than that of the non⁃metallic target. The security inspection software system can detect the dangerous metal products according to the difference of reflected signals.
