Direction Finding with Gain/Phase Errors and Mutual Coupling Errors in the Presence of Auxiliary Sensors

Table 1

Mean and variance of gain and phase coefficients for all uncertain sensors at SNR = 0 dB and SNR = 20 dB. True values are 𝐺₁=0.80, 𝐺₂=1.25, 𝐺₃=1.53, 𝐺₄=0.75, and 𝐺₅=1.36; 𝑃₁=0.6283, 𝑃₂=−1.0472, 𝑃₃=−0.6283, 𝑃₄=0.7854, and 𝑃₅=−0.3142 (rad).
