English Description：
L1svd algorithm, a DOA estimation algorithm based on compressed sensing, successfully applies compressed sensing theory to spatial spectrum estimation. The algorithm can not only estimate the direction of wave with high accuracy, but also estimate the direction of wave of coherent and incoherent sources at the same time. When there are multiple snapshots, the algorithm introduces singular value decomposition to reduce the dimension and greatly reduce the computational cost At the same time, the algorithm transforms the objective function into a SOCP problem, which can be solved by a large number of toolkits.
