Abstract

Localization plays an important part in bistatic SAR (BiSAR). The accuracy of traditional localization method for BiSAR depends on whether the measurement position of platforms are precise or not. The lower the measurement accuracy, the higher imprecise the localization error of targets. This paper proposes a blind localization method with multi-point scatterer targets for BiSAR, which don't relays on the Global Position System (GPS) or Inertial Navigation System (INS) deeply. Firstly, Keystone Transform (KT) is used to realize range cell migration correction (RCMC). Next, the fractional Fourier transform (FrFT) is applied to estimate Doppler parameters. At last, establishing localization equation with the estimation parameters, and the Differential Evolution (DE) Algorithm is devoted to solve localization model constructed above. The effectiveness of the localization method proposed in this paper has been demonstrated and illustrated by numerical simulations.
