Abstract

Abstract

ESPRIT can estimate one direction of signals utilizing a single shift-invariance property of the sensor array. A novel method, i.e. dual-invariance ESPRIT, is proposed in the paper which can estimate two directions of incident signals utilizing two shift-invariance properties of a special sensor array which consists of three shifted subarrays. The new method is very fast and can get naturally paired direction estimates. What is more, the subarray geometry is arbitrary so that accurate estimates can be obtained by using an appropriate subarray geometry.
