#### Abstract

A (1, -1)-matrix will be called a bent type matrix if each row and each column are bent sequences. A similar description can be found in Carlisle M. Adams and Stafford E. Tavares, Generating and counting binary sequences, IEEE Trans. Inform. Theory, vol. 36, no. 5, pp. 1170-1173, 1990 in which the authors use the properties of bent type matrices to construct a class of bent functions. In this paper we give a general method to construct bent type matrices and show that the bent sequence obtained from a bent type matrix is a generalized result of the Kronecker product of two known bent sequences. Also using two known bent sequences of length 2^{2k-2} we can construct 2^{k-2} bent sequences of length 2^{2k} more than in the ordinary construction, which gives construct 10 bent sequences of length 2^{2k} from two known bent sequences of length length 2^{2k-2}.
