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
