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

A radar system for mapping a scatterer in a structure, comprising:

• a transceiver module on a movable platform moving along the structure and being arranged for:
• transmitting, while the platform is continuously moving along the structure, from one or a multiple number of positions on the moving platform exterior to a structure, a wall probing radar signal towards the structure;
• receiving, while the platform is continuously moving along the structure, at one or a multiple number of positions on the moving platform exterior to the structure, radar signals that have been reflected by scatterers in the structure;
• and
• a processor arranged for:
• filtering, from the received signals, reflection information of a specific scatterer at a specific position;
• identifying a geometry of the specific scatterer, based on the reflection information,
• wherein the filtering step comprises applying a phase change algorithm corresponding to a specific scatterer type, wherein the phase change algorithm uses at least two different measurement positions of the moving platform as the platform is continuously moving to identify the specific scatterer;
• and
• mapping the specific scatterer in the structure.

An article of manufacture comprising a non-transitory computer usable medium having encoded thereon a set of instructions executable by a computer system to perform one or more operations for mapping a scatterer in a structure, the set of instructions comprising:

• filtering reflection information of a specific scatterer at a specific position, from signals that have been received, at one or a multiple number of positions on a moving platform exterior to a structure, while the platform is continuously moving along the structure, the received radar signals propagating from scatterers after a wall probing radar signal has been transmitted, from one or a multiple number of positions on a moving platform exterior to a structure, towards the structure, while the platform is continuously moving along the structure;
• identifying a geometry of the specific scatterer, based on the reflection information,
• wherein the filtering step comprises applying a phase change algorithm corresponding to a specific scatterer type and at least two different measurement positions of the moving platform while the platform is continuously moving along the structure;
• and
• mapping the specific scatterer in the structure.
