Beamforming plays an important role in the array radar anti-interference.However, the interference targets with fast speed may move out of the narrow null area of the beampattern.A null broadening method with Socks robust adaptive beamforming for frequency diverse array (FDA)-multiple-input and multiple-output (MIMO) systems is proposed in this paper.The projection preprocessing and windowing functions are applied to obtain stable beampatterns.Then, a novel null broadening method based on the covariance matrix reconstruction is realized by setting Baby Tee artificial fluctuations around each actual jammer.

Finally, a new convex optimization model is established and solved to estimate the desired steering vector.Numerical simulations results verify the effectiveness of the proposed method.
