摘要：
The work presented in this paper proposes two passive antenna array designs for Side Looking Airborne Radar application toward maritime pollution surveillance. The first proposed design is a slotted waveguide passive array for the SLAR operation, having a cladded radome that meets the requisites at the simulation level, and has been validated with measurements. Second is an aperture coupled microstrip antenna array design which offers better control over the design parameters for achieving the intended performance. Both designs have lower weight compared to the other SLAR arrays while achieving narrow beam in azimuth, and 100 MHz bandwidth in X-Band.
