Abstract :
Interferometric fringes can be formed from couples of complex SAR images measured,with the a radar system positioned at two closely spaced looking angles. Indoor SAR imaging presents the advantage, over airborne and spaceborne SAR, of using very well defined geometries which gives the possibility to exploit it for validating SAR focusing algorithms and their interferometric applications. Furthermore, indoor SAR measurements can be conducted with frequency bandwidths not available yet to present airborne and spaceborne SAR systems.
