Aiming at the difficult in hardware realization of random measurement matrix
we construct a deterministic measurement matrix based on composite chaotic mapping.The composite chaotic mapping that based on Tent mapping and Logistic mapping
has stronger randomicity and initial value sensitivity.Sampled the composite chaotic mapping sequence with large distance
and then do linear transformation to the sampling sequence.Finally
we construct the measurement matrix with the linear transformation result.We prove that the measurement matrix elements have enough statistically independent
and the measurement matrix can satisfies restricted isometry property (RIP) with large probability.The simulation result shows that our matrix has the similar performance to Gaussian random matrix
and better than Toeplitz deterministic measurement matrix and Logistic deterministic measurement matrix.
