Research on adaptive sidelobe cancellation technology of AESA

Abstract： Adaptive sidelobe cancellation radar systems can effectively resist active jamming from the sidelobe direction. Based on the analysis of the operating principle of AESA adaptive sidelobe cancellation, on the base of auxiliary antenna configuration design, the cancellation performance of the adaptive sidelobe cancellation radar system was simulated systematically and comprehensively in view of the change of jamming source relative to radar angle and the difference of radar antenna pattern. The simulation results show that when multiple single polarization jamming sources and single polarization jamming source is used for jamming the adaptive sidelobe cancellation radar system respectively, the blinking jamming and polarization jamming are not ideal. Therefore, jamming combination of blinking jamming with multiple jamming sources and polarization jamming is advised as the sidelobe jamming strategy against adaptive sidelobe cancellation radar systems.
