The new generation of European E-scan fighter radars

Two European programmes towards an airborne E-scan radar have obtained major attention: AMSAR, a generic demonstrator for developing the technology required for an AESA radar and for proving its operational capabilities, and CAESAR that paves the way to the next generation of radar for Eurofighter. Future sub-array AESA architectures and multi-channel receivers will enable efficient jammer suppression by use of Adaptive Beam Forming. The technology basis of T/R-Modules will move to Gallium- Nitride, promising improvements in efficiency, output power and miniaturisation.
