A radar transceiver (4, 5) is mounted on a pantograph (31) for scanning over a surface of interest so that sub-surface features may be investigated and imaged. A computer controls at least one stepper motor driving an X-Y scanner (34) for determining the location and operation of the pantograph. The arrangement is useful in a SAR stepped frequency continuous wave imaging system using a two-dimensional boustrophedral or random scan of the surface and analysing both amplitude and phase components of the received signal.
