The sidelobe has many ripples in condition of small training sample size and the diagonal loading technology is applied to this method, which improve the convergence speed of sidelobe. We also study the pattern control of area array. The effectiveness of this new method is illustrated by the designed simulations.5. Adaptive sidelobe cancellation is a important part of phase array radar. To realize low sidelobe and suppressing the interferer the antenna technique and signal process are combined.
