The estimation for the direction of arrival based on sparse array

The estimation method for the Direction of Arrival problem based on compressed sensing is proposed. In the case of sparse array antenna, the receiving signal from absence elements can be reconstructed by using the theory of compressed sensing. In this work, we set the scene that the antenna elements reduce greatly. But we can still estimate the result almost the same with the result of full array antenna by sparse sampling. Simulation results show that this method can rebuild the data well.
