When Magnitude Suffices: Reconstructing Time-Domain-Gated Microwave Signals Without Phase on a Thoracic Phantom
We show that, on one calibrated measurement configuration, the gated magnitude the VNA would give can be reconstructed from a magnitude-only sweep of a spectrum analyzer with a tracking generator (SA).

Key points
- Time-domain gating separates the arrivals that form a microwave S-parameter measurement.
- The test object is a torso phantom with lung-shaped compartments whose filling takes eleven dielectric states, each held out in turn.
- On $S{11}$ the reconstruction from SA input reaches a shape error of 0.08 dB$^2$ with a state ordering of 0.81.
- This matches the reconstruction from VNA input.
