Off-Grid DOA Estimation for Wideband LFM Signals in FRFT Domain Using the Sensor Arrays
For the direction-of-arrival (DOA) estimators based on sparse signal representation, the feasibility and precision are greatly restricted by the inherent limitation of the predefined spatial discrete grids. In this paper, based on the high aggregation characteristic of wideband linear frequency modu...
