1 The Fundamentals of Angle-of-Arrival Assisted Relative Interferometry (ARI)

2 Frequency Modulated ARI (FM-ARI) FM-ARI RADAR FM RADAR

3 An Example of FM-ARI Dense Target Cluster Localization (Simulation)

4 Fusion, Bandwidth, Response Rate, and Resolution After IF Conversion… …gaps in time result! After IF Conversion… …gaps in time result! Gaps in time cloud the spectrum! Must resolve or targets will be obscured! FM-ARI RADAR forms 3D target positions by fusing three sets of independent information: 1.Chirp response of TxA 2.Chirp response of TxB 3.Phase difference between TxA and TxB FM-ARI RADAR forms 3D target positions by fusing three sets of independent information: 1.Chirp response of TxA 2.Chirp response of TxB 3.Phase difference between TxA and TxB

5 Software-Defined Radio (SDR) Implementation Feasibility Study

6 Resolving Complex Targets in Multipath Environments Using ARI RADAR Systems Jonathan Friedman, Dustin Torres, Newton Truong, and Mani B. Srivastava
