Ultrawideband Discharge Source DOA Estimation Method Using Multiple Baseline Wideband Time-Domain Interferometry with Hilbert Transform

Figure 7

Monte Carlo simulation of the RMSE of DOA estimation under different antenna array conditions: (a) simulation results under different baseline lengths with the following parameters: azimuth angle = 10°, elevation = 45°, SNR = 10 dB, antenna number = 4, and 1000 realizations and (b) simulation results under different antenna numbers with the following parameters: azimuth angle = 10°, elevation = 45°, SNR = 10 dB, baseline length = 8 m, and 1000 realizations.
