Open the CIPO recordAbstract From the Canadian patent
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.

Why it's free to use
- Filed September 13, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 13, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 13, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
