Abstract :
An X-band radar has been built with an antenna capable of rotational speeds up to 1400 rev/min, and a display system which follows at these speeds. This enables only one or two pulses per beam-width to be displayed, the pulses received from successive looks at the sea clutter being de-correlated. A conventional fluoride p.p.i. tube and a storage p.p.i. tube were used simultaneously. The resulting improvements from de-correlation and integration are demonstrated.
