The Diffraction Tomography Theorem states that the full response of a weak scattering body to illuminating monochromatic plane waves coming from all directions is the Fourier spectrum of the reflectivity. This well known fact has been exploited in seismic and acoustic analyses but not as much for radar, as bistatic receivers have rarely been used. This paper intends to recall the DTT, and illustrate the immediate implications in the case of constellations of low frequency spaceborne Synthetic Aperture Radars (SAR), whose performance are severely limited by bandwidth restrictions imposed by ITU regulations. We will show that each passive receiver provides a specific region in the wavenumber domain. Those regions can be combined to form a bigger one by properly positioning the receivers, therefore increasing spatial resolution. This process is conceptually analogous to forming a tessellation using a number of small tiles, hence the title of this paper. Using this concept, we will show that the use of N additional passive receivers allows an N-fold increase of the slant range resolution. For example, the use of just two additional receivers would increase the slant range resolution achievable at P-band from 25 m to about 8 m, still respecting the 6 M H z limit.
