Summary:A non-conventional design approach for low-cost small satellites synthetic aperture radars (SAR) acquiring ambiguous images for ship monitoring is proposed here. The resulting system design allows using narrow antennas, for large nominal swaths, with width compatible with the largest side of a CubeSat while keeping a reasonably low transmit power by reducing the imaged swath to a fraction of the nominal one. It is shown that for an antenna of size 0. 3x2.8m and a transmit power of 100 W, adequate imaging performances for the application can be obtained over a swath of 25 km at an incidence angle of 30° for a sensor orbiting at 500 km.
