Abstract

There exist few rapid reconstruction methods for applications that use multistatic radar for targets in the near field such as vehicle navigation and personnel screening. Fourier accelerated multistatic imaging (FAMI) is a method that combines the rapid reconstruction speed of Fourier-based imaging algorithms with the flexibility of algebraic algorithms that allow arbitrary radiation patterns and antenna placement. Many of these new applications image in the near field of the individual antennas of a multistatic array, however, FAMI contains approximations that require the target to be in the far field of each antenna. Stretched-phase FAMI (SP-FAMI) overcomes this limitation and allows imaging in the Fresnel region of the antennas so that targets may be very close to the array while retaining the computational benefits of Fourier reconstruction. As radar wavelengths decrease with a corresponding increase in resolution, SP-FAMI allows the imaging of nearby targets that would otherwise be too close for FAMI to image accurately.
