Fusion, Bandwidth, Response Rate, and Resolution
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 TxA2. Chirp response of TxB3. Phase difference between TxA
and TxB
