Airborne radar has evolved from early systems where almost all radar characteristics were fixed to todaypsilas highly flexible, software-driven systems. The most recent advance has been the widespread adoption of active electronically scanned array (AESA) antennas, which has given the system designer unprecedented control of antenna characteristics. However, in common with most conventional radars,...
It is commonplace to use an unweighted transmit aperture and a weighted receive aperture in radars utilising active electronically steered array (AESA) antennas. The preferred receive weightings are usually Gaussian or Taylor as these are perceived to give the best compromise between loss of main-beam directivity, minimised main-beam dilation and excellent sidelobe control. However, this is only part...
The UK Ministry of Defence is starting to introduce in to service the next generation of radar technology. This technology brings with it the potential for significant improvements in performance for airborne, ground based and naval applications as well as benefits for through life capability maintenance. However there are a number of challenges facing the implementation of advanced radar technology...
