It used rotating antennae and a PPI (Plan Position Indicator) display to allow its use for ground mapping.
[5] Magnetrons based on this captured 9 cm wavelength design, the British CV64, were produced, the German LMS10 operating with a power of 10 kW.
Using this array, rather than a parabolic dish, gave an extremely compact antenna, with only a shallow protrusion, which was well-suited for aircraft carriage, particularly when needed to rotate.
The array could rotate at the high speed of 400 rpm, fast enough that the PPI display did not require the usual long persistence phosphor.
The first design used two fixed sets of deflection yokes, at right angles to each other, and varying the drive signal to both of them by means of a goniometer.
[12] The rotating deflection yoke was an advantage for naval use, where multiple displays were provided for the same radar set.
