FODDBASA (Foreign Object Debris, Drone and Bird-Aircraft Strike Avoidance )
The FODBASA system is an integrated sensor system solution consisting of a FODA sub-system and a BASA sub-system. Each sub-system in turn consist of one, two or multiple individual radars. For optimal performance it is usually recommended to use two or more radars. Likewise, it is recommended to use two or more high-resolution cameras.
The FODA sub-system is based on Ka-band technology as a compromise between high resolution capability and reduced susceptibility to clutter and attenuation from precipitation but also price. The coverage range will typically be 3 km. The BASA sub-system is based on X-band technology that provides enough resolution capability and at the same time all-weather performance. An extended coverage range up to approximately 10 km is provided. Two separate subsystems are responsible for coverage of a flat 360° horisontal sector and a vertical (elevation) corridor centered along the runways respectively.
FODA sub-system and a BASA sub-system can transfer complementary information in a way to warrant dual-band operation covering the critical runway surface zone.
