METHOD FOR ESTIMATING DIRECTION OF ARRIVAL BASED ON CONTINUOUS COMPRESSIVE SENSING AND APPARATUS THEREFOR

摘要

According to one embodiment of the present invention, provided is a method for estimating an angle of arrival based on continuous compressive sensing, which comprises the steps of: receiving a target signal in the time domain via a sensor array; performing a Fourier transformation on a target signal received by the sensor array at a predetermined time period to generate a plurality of single measurement signals converted into a frequency domain, and generating a multi-measurement signal composed of the plurality of single measurement signals; generating a total-variation norm minimization problem for estimating the angle of arrival based on the multi-measurement signal; transforming the total-variation norm minimization problem into its dual problem algorithm using a Lagrange concept; and estimating the angle of arrival of the target signal with the dual problem algorithm.
