%X The two-dimensional ADBF method at subarray level is studied. The signal model of ADBF at subarray level is presented which is suitable for plane phased array. The conventional two-dimensional ADBF at subarray level is given which is generalized by one-dimensional ADBF at element level. The two-dimensional ADBF at subarray level based on subspace projection is introduced, and the desired quiescent pattern can be achieved in the absence of jammer, so the conversion problem between adaptive and non-adaptive work modes is resolved, while in the presence of jammer, the jammer is suppressed effectively, and the sidelobe level is improved markedly compared with the conventional method. Simulation results indicate the validity of the introduced methods.
