Abstract The sensors for measuring water incurved surface radome honeycomb based on the dielectric constant modulation is developed. The dielectric constant indicates the relative capacity of the dielectric to store the electrostatic energy in the electric field. The dielectric constant of water is much larger than the dielectric constant of air and materials of radome, so it can be used to detect the cellular water of radome by the method of the dielectric constant modulation. In order to ensure the test sensitivity, the sensor plates must be closely attached to the measured structure. The shape of radome determines that the plate should be a flexible structure, which can fit the shape of curved surface, the sensor probe is composed of multi plates with a copper bar welding method, and the structure is optimized by using ANSYS software. Through testing the water of honeycomb structure, the experimental results show that the sensor can realize the water detection of honeycomb structure, and has high test sensitivity and repeatability.
