On the impact of the antenna radiation patterns in passive radio sensing: dataset

The measurement sessions took place in a hall with size 6.15 m × 14.45 m and floor-ceiling height equal to 3.35 m.  TX and RX nodes are spaced d=4.00 m apart, while the LOS is horizontally placed at h=0.99 m from the floor.

The received power P is measured using a real-time spectrum analyzer (SA) with a built-in tracking generator. The SA tracks N=401 frequency points equally spaced with Δf=1.25 MHz. Further settings are detailed in the paper:
