Low-angle estimation method for meter-wave radar via matrix completion

摘要

The deficiencies of array elements causes the decrease of angle survey precision when detect low-angle estimation. In order to solve this problem, this paper transform the data missing matrix which isn't meeting the condition of the SIP into appropriate one based on the MC theory by using the Hankel matrix's properties. Then according to the ILAM algorithm and the generalized MUSIC algorithm, the method can recover the complete data matrix and get the angle messages in the reality. The simulated experiment verifies the method effectiveness.
