From: Extending coprime sensor arrays to achieve the peak side lobe height of a full uniform linear array
ECSA and equivalent full ULA beam patterns for uniform tapering. The top shows the formation of the beam pattern of an ECSA with coprime pair (2,3), uniform tapering, and 19 and 20 sensors in the extended subarrays. The bottom compares the beam patterns of the ECSA with the beam pattern of the equivalent full ULA.
