  • Method of detecting a scatterer in a structure, a radar system and a computer program product
    Patent number: 9851439
    Abstract: The invention relates to a method of detecting a scatterer in a structure, such as a building structure. The method comprises the steps of transmitting from one or a multiple number of positions exterior to a structure, a wall probing radar signal towards the structure. The method also comprises the step of receiving, at one or a multiple number of positions exterior to the structure, signals that have been reflected by scatterers in the structure. Further, the method comprises the step of filtering, from the received signals, reflection information of a specific scatterer at a specific position. In addition, the method comprises the step of identifying a geometry of the specific scatterer, based on the reflection information. The filtering step comprises applying a phase change algorithm corresponding to a specific scatterer type.
