Abstract: A radar reflector which can be deployed from an aircraft and is intended to fly freely after deployment, and which includes multiple reflector surfaces that are essentially plane in an operative state and which issue in pairs in opposite directions from an essentially plane base plane. The radar reflector before deployment can be stored compactly, packed up into the minimum possible volume. This facility for packing the radar reflector up has been achieved in that its reflecting main surfaces have each been divided up by means of specially aligned buckled folds into a plurality of parts which can be folded in towards one another when the reflector is to be folded up.

Abstract: A radar reflector including a first and a second radar corner. The radar corners are formed by an essentially rectangular first flat plate and a second and a third essentially flat plate arranged perpendicular to the first plate at two perpendicular edges of the first plate and to meet the two edges of the first plate. The second and the third plates of the first radar corner are arranged to meet two different perpendicular edges of the first plate than the second and third plate of the second radar corner. In order to obtain a less bulky storing and a more easily controlled ejection process the second and third plate of each radar corner are rotatable at the meeting edge of the first plate from a folded position in which the plates are essentially parallel with and close to the first plate to an unfolded position in which the plates are essentially perpendicular to the first plate.

Abstract: This invention concerns a repeater jamming transmitter (2), and a casing arrangement with repeater jamming transmitter. The repeater jamming transmitter (2) comprises transmitter antenna (7), receiver antenna (8) and electronics part (10) with amplifier and control circuits. In order to avoid self-oscillation caused by leakage between the transmitter antenna (7) and the receiver antenna (8) and to maintain the isolation a special connection arrangement (7,8,10) is included in the repeater jamming transmitter. By means of the connection arrangement the amplification of the repeater jamming transmitter can be increased without self-oscillation arising.
