- FIGURE 1
Measurement setup: The beige antenna array (DLR UNITAS) is used to receive the satellite signals, and the blue triangular-formed antenna is used to radiate the jamming signal.
- FIGURE 2
Signal tracking structure of multi-antenna receiver with N antenna channels and M satellite channels; the proposed compensation unit is marked in red.
- FIGURE 3
Movement of the blue jamming antenna around the UNITAS antenna array in Scenario 2.
- FIGURE 4
JSR and power of eigenvalues of the pre-correlation covariance matrix over time; both parameters are estimated by the receiver. Subfigure (a) shows Scenario 1’s JSR, (b) shows Scenario 2’s JSR, (c) shows Scenario 1’s eigenvalues, and (d) shows Scenario 2’s eigenvalues.
- FIGURE 5
Scenario 1’s time evolution of double-differenced carrier-phase residuals per satellite: (a) shows Single Antenna Mode, (b) shows the Without Phase Compensation Mode, and (c) shows the With Phase Compensation Mode; (e) shows the overall RMS residual values per GNSS along with (d) the skyplot.
