From: Extending coprime sensor arrays to achieve the peak side lobe height of a full uniform linear array
Beam patterns of the subarrays with four and five sensors, the CSA and the full ULA. The blue dashed-dot line is subarray 1 beam pattern in 10 log10(·) scale. The red dashed-dot line is subarray 2 beam pattern in 10 log10(·) scale. The black solid line is the CSA output power spectral density. The green dashed line is the equivalent full ULA’s beam pattern in dB.
