Abstract :
A new generalized sidelobe canceller (GSC) is proposed to solve the steering error problem caused by fast target maneuvering or array imperfections. The proposed GSC uses the monopulse technique to identify the steering error. Seperate sum and different channels are used for estimating the monopulse ratio. While interferences are removed by adaptive beamforming, fixed-weight sum and difference beampattems are applied to estimate the steering error. Simulation results show that the proposed GSC can solve the steering error and track the target even under severe jamming conditions.
