From: Enhanced "vector-cross-product" direction-finding using a constrained sparse triangular-array
Aperture extension effect of the proposed array configuration. (a) The CRBs of the direction-cosines versus SNR, for three incident sources; same setting as in Figure 3b. Both the CRBs with and without the scalar sensor are plotted. (b) The CRBs of the direction-cosines versus inter-sensor spacing Δ/λ, for three incident sources; same setting as in Figure 3b at SNR = 30dB. Both the CRBs with and without the scalar sensor are plotted.
