Summary:
This paper proposed a new approach of linear sparse array antenna design with a hybrid technique of non-uniform elements spacing and combinatorial cyclic different sets (CDS) to achieve high resolution requirement in radar applications. As an example, the spatial dimension of 64 elements linear microstrip full array configuration (d = 0.7λ) is reduced to 32 elements linear sparse array configuration using the proposed technique. The simulation result showed the sparse array beamwidth resolution was improved compared to full array configuration with small sidelobe level degradation.
