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.

Method of detecting a scatterer in a structure, a radar system and a computer program product

The invention relates to a method of compensating sub-array or element failure in a phased array radar system. The method comprises the step of defining a virtual array comprising a multiple number of virtual transceiver tiles preferably arranged halfway all connection lines interconnecting a transmitter tile to a receiver tile. Further, the method comprises the steps of performing phased array radar measurements, and estimating radar data associated with a first transmitter/receiver combination by using radar data associated with a second transmitter/receiver combination, wherein the virtual transceiver tile of the first transmitter/receiver combination substantially coincides with the virtual transceiver tile of the second transmitter/receiver combination.
