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
