ABSTRACT:
A radar for an aircraft (1) comprises end-plates (4a, 4b) mounted at the tip's of two pairs of aircraft wings (2a, 2b, 3a, 3b). Each end-plate carries a sideways-looking phased array (6) whose beam is unobstructed by aircraft structure. The array can be made to have a large area, thus producing a narrow beam, steerable over a large solid angle. In one embodiment, the end plates (4a, 4b) incorporate fins (5a, 5b) which replace the aircraft fin to afford lateral stability and control.
