Abstract：This paper presents a low complexity and high accuracy algorithm which can be used in wireless communication，imageprocessing，radar monitoring and other fields. This algorithm adopts the method of direct calculation plus partial iteration. Unlike otherordinary encryption algorithms，this algorithm is convenient and simple，and its product is Khatri-Rao. The algorithm is the carrier，including SVD decomposition algorithm，its role is to encrypt data processing or approximate estimation. Computer simulation and actualdata acquisition show that the algorithm has high accuracy，simple implementation，strong feasibility and practicability.

Keywords：Khatri-Rao integral solution；SVD algorithm；left and right singular vector
