Monopulse Aerials for Airborne Radars

The paper begins by summarising the characteristics of a number of mono-pulse aerials applicable to airborne radar. For such a use, it is often important that the aerial has low side lobes. Good sidelobe performance may be obtained with a flat plate array which can have an accurately controlled aperture distribution and is free from feeder blockage and spillover. The development of a novel flat plate sandwich wire array is described and some experimental results are presented.
