l Strong penetration: Strong penetration for non-polar substances. Many nonmetallic nonpolar materials absorb less rays in this band and, therefore, can be used to probe the internal structure of the material. For example, ceramics / cardboard / plastic products / foam are transparent to this band of electromagnetic radiation, and can also be used for airport / station safety monitoring, such as exploring machinery / explosives and drugs, or for circuit board welding detection.

Large measuring range, small blind area. The maximum range can reach 120m, and the blind area can reach 8cm.

Small beam angle, small antenna size, easy installation. It is less affected by the size of the tank receiver and obstacles
