Through‐wall radar allows for remote intelligence of building interiors including stand‐off detection and tracking of persons inside a building. However, reliable radar tracking of people inside a building is not trivial. Conventional, monostatic through‐wall radar measures the backscatter of moving people. The backscatter from a human is relatively low compared with the scattering from building features or furniture. The forward scatter radar (FSR) concept is proposed to detect and possibly track moving people in specific areas of a building. The FSR concept exploits the forward scatter (FS) of objects, which is typically larger than their backscatter; for humans a factor of 20 is possible. It is shown that stand‐off detection of moving people inside a building can be performed reliably and consistently based on their FS.
