PURPOSE: A radar systems having a synthetic aperture is provided to perform a signal processing in a simple method and to implement aviation stability. CONSTITUTION: A SAR(Synthetic Aperture Radar) system has a radar antenna(ANT). The radar antenna includes at least one part antenna(Pan1, .,Pan6). Each part antenna includes multiple phase centers(Rad), a transmission/receiving module(TRM) and a signal processing unit. The transmission/receiving module is allocated to the phase centers. The signal processing unit performs a coherent process of the signal of a radiator. The signal processing unit includes a hybrid beam forming module(HBFM). The hybrid beam forming module performs digitalization of an analog receipt signal. |
