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

Figure 8

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