Blue Joker was an experimental moored balloon-mounted, airborne early-warning radar project developed by the Royal Radar Establishment (RRE) starting in 1953. The idea was to position the radar high in the air in order to extend its radar horizon and allow it to see low-flying aircraft. Ground reflections were filtered out using a moving target indicator (MTI) system. Two examples were built and tested in the late 1950s, but the project was cancelled in 1960 as part of the Linesman/Mediator efforts.
