The proposed array configuration. The triangular SS-EMVS in Fig. 1 is located at the origin.The scalar array whose unit is ex is extended along y-axis. The inter-sensor spacing in sub-array 1 is D1 and the inter-sensor spacing in sub-array 2 is D2, respectively, where D2=m1D1 and D1>Δx,yλ/2. Similarly, the scalar array whose unit is ez is extended along x-axis. The inter-sensor spacing in sub-array 3 is D3 and the inter-sensor spacing in sub-array 4 is D4, respectively, where D4=m2D3 and D3>Δy,zλ/2
