1. A mosaic omnidirectional radar scanning system for surveillance aircraft comprising:

  • a pair of sending and receiving radar antennae substantially covering in total a 360* solid angle of transmission and reception, synchronized motor means for driving said plurality of antennae in unison;

    a spherically shaped display element including a transparent sphere having a fluorophor-coated inner surface, a pair of oppositely directed electron-beam guns mounted within said sphere, said guns covering substantially a 360* solid angle of projection, and operating in synchronism with said antennae;

    raDar pulse generating means, a pair of radar transmitters connected respectively to each of said sending radar antennae, a pair of radar receiver means, a pair of spot-generator means actuated by the presence of a received signal from a respective radar receiver means, means for directing a received signal to one of said electron guns for display upon the inner surface of said sphere, and saw-tooth wave generator means for biasing said spot-generator means such that the size of a display signal is related to the distance from a detected object.
