In order to solve the great computational complexity in compressed sensing radar imaging due to a large observation matrix, an approximate observation model based approximate message passing algorithm is proposed in this paper. It uses inverse chirp scaling operator to approximate the large observation matrix in compressed sensing radar imaging, thereby effectively reducing the computational complexity by the current mature decoupling technology, and in the meantime, the approximate message passing is used to improve convergence rate. The theoretical analysis and simulation show that compared to the currently used compressed sensing radar imaging methods, the proposed method exhibits higher convergence rate while suffers same computational complexity in each iteration. It realizes compressed sensing radar imaging of non-complete observation data.
