Abstract
- Linear array maneuvering synthetic aperture radar (SAR) can push the limitations of classical SAR on foresight 3-D imaging, which has captured the attention of worldwide radar researchers for a long time. To reconstruct the position of foresight target, this article puts forward a nonlinear chirp scaling (NLCS) method for 3-D foresight linear array maneuvering SAR (FLAM-SAR). According to the novel geometry configuration, an NLCS operation is adopted to equalize the space-variant Doppler frequency modulation rate. The simulation results of the array point scatterers and real airplane target model are used to prove the validity of theoretical derivation and validate the 3-D imaging capacity of FLAM-SAR.
