Geometric Configuration Design and Fast Imaging for Multistatic Forward-Looking SAR Based on Wavenumber Spectrum Formation Approach

Multistatic forward-looking synthetic aperture radar (Mu-FLSAR) has the potential of high-resolution imaging with short time, which can improve transmitter’s survivability, by coherently fusing simultaneously observed measurements multiple receivers. However, combined performance strictly depends on an appropriate geometric configuration among transmitter and receivers because application limits flight directions In this paper, to design a for Mu-FLSAR, wavenumber spectrum formation (WSF) approach is proposed based projection relationship between support regions (WSRs) parameters. On one hand, projected pattern WSRs deduced, point spread function (PSF) analyzed. Based feature kernel WSR, formed master receiver, features parameters, including time azimuthal angle, WSF method visually quickly deduce parameter salve other designed wavenumber-dependent fast polar format algorithm (WF-PFA) efficiently reconstruct targets relying WSRs. Simulation results verify method.
