Abstract
Abstract A low data rate display is provided using light sources to represent range, and mechanical scanning of azimutn. In one embodiment a rotating arm synchronized to a rotating antenna has a number of light sources mounted along the length thereof each of which corresponds to a particular range and each of which is coupled to a particular range gate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
70 words
Apparatus for displaying low data rate range and azimuth information from an object location system having an antenna rotating in azimuth and a plurality of range gates, comprising: a radial arm rotating in synchronism with a scanning antenna; light bulbs arranged along the length of said arm, each of said light bulbs responsive to a different range gate; and a screen adjacent said light bulbs for displaying the illumination thereof.
Claim 2
Dependent Claim
70 words
Apparatus for displaying low data rate range and azimuth information from an object location system having an antenna rotating in azimuth and a plurality of range gates, comprising: a radial arm rotating in synchronism with a scanning antenna; light bulbs arranged along the length of said arm, each of said light bulbs responsive to a different range gate; and a screen adjacent said light bulbs for displaying the illumination thereof.
Claim 3
Dependent Claim
11 words
Apparatus as defined in claim 1, wherein said screen is phosphorescent.
Claim 4
Dependent Claim
21 words
Apparatus as defined in claim 1, wherein said screen is phosphorescent and fluorescent and said light bulbs are ultraviolet light bulbs.
Claim 5
Dependent Claim
24 words
Apparatus as defined in claim 1, further including at least one edge lit panel adjacent said screen, said edge lit panel having markings thereon.
Claim 6
Dependent Claim
34 words
Apparatus as defined in claim 4, wherein said markings are concentric circles indicating range gradiations, said apparatus further including a second edge lit panel having a grid network of horizontal and vertical lines thereon.
Claim 7
Dependent Claim
26 words
Apparatus as defined in claim 1, further including means for projecting the information from said rotating light sources onto a screen for providing an enlarged display.
Claim 8
Dependent Claim
42 words
Apparatus as defined in claim 1, further including a stationary panel having a plurality of lights thereon, said stationary panel arranged parallel to said screen whereby illumination of any of said lights on said stationary panel would be displayed on said screen.
Claim 9
Dependent Claim
96 words
Apparatus for displaying low data rate range and azimuth information from an object location system having an antenna rotating in azimuth and a plurality of range gates, comprising: an opaque disc having a slot therein rotating in synchronism with a scanning antenna; a screen; nd a number of optical rings, said rings being illuminated in response to an output from range gates, said disc being arranged intermediate said optical rings and said screen, whereby said screen will be illuminated at a point corresponding to the position of said slot and the illumination of a particular ring.
Claim 10
Dependent Claim
96 words
Apparatus for displaying low data rate range and azimuth information from an object location system having an antenna rotating in azimuth and a plurality of range gates, comprising: an opaque disc having a slot therein rotating in synchronism with a scanning antenna; a screen; nd a number of optical rings, said rings being illuminated in response to an output from range gates, said disc being arranged intermediate said optical rings and said screen, whereby said screen will be illuminated at a point corresponding to the position of said slot and the illumination of a particular ring.
