Abstract

1369084 Pulse radar; aerials TEXAS INSTRUMENTS Inc 9 July 1971 [15 July 1970 (2)] 32369/71 Headings H4A and H4D [Also in Division G4] An airborne pulse radar incorporates an aerial having an elevational radiation pattern broad enough to detect an airport and an azimuthal radiation pattern which is narrow and which is swept in azimuth, height-signal producing means, and display means responsive to radar echoes and the height-signal for visually indicating an approaching airport in perspective Figs. 19(a) to 19(d) (none shown). There may be corner reflectors on the runway-boundaries, and the embodiment operates in the 33 to 38 GHz band. General arrangement, Fig. 4.-In the embodiment, PPI and type B displays are provided for in addition to the perspective display and the display medium is a direct-view storage tube 70. Aerial, Fig. 5.-The aerial consists of an edge-slotted waveguide array 152 with regularlycut slots alternate ones of which are parallel and sloping in the same direction with another set of parallel slots sloping in a different direction (see also Fig. 8, not shown); a quarter-wave polarizer 154 to convert horizontal to circular polarization and made of regularly spaced narrow metallic vanes in a low-loss dielectric ; and a horn 150. A housing 120 has attached to it a streamlined housing 146 and a fibreglass radome 148. The aerial is swept Œ15 degrees relative to "head-on" by a D.C. torque motor having an output shaft 116, a permanent magnet rotor and a toroidal stator coil energized by a semi-conductor driving circuit, Fig. 9 (not shown); oscillation is assisted by a spring 134. The entire waveguide assembly is pressurized with a halogonated hydrocarbon. Radar receiver, and monitoring, Fig. 10.-A local oscillator 224 is maintained at a frequency such as to give the correct I.F. at the output of mixer 216, 218, either by automatic, 246, or manual, 252, means. If the automatic frequency control means cannot operate correctly, a light 254 is energized; the light is also energized if the peak power output of the transmitter falls below a predetermined magnitude or if mixer diode bias current fails. The receiver includes a logarithmic amplifier 232, time-varied gain control 230 and a fast time-constant operation on the video signal to prevent saturation of the display. A line 258 produces a train of pulsed signals at I.F. to produce horizontal lines on the radar display for indicating correct operation of the aerial scan &c. Radar transmitter.-A thyratron is triggered from a synchronizer and, via a pulse forming network and a pulse tranformer, causes a tunable magnetron to feed R.F. pulses to the aerial via a circulator, Fig. 11 (not shown). Sweep generation. Fig. 12.-For the perspective display radio or barometric altitude (h) signals are fed to a limiter 350 to inhibit operation for altitudes less than fifty feet, and thence to shaping networks 352, 354, 356 (see Division G4). Displays. Conventional P.P.I. and type B displays may be selected. A runway may appear as a dark trace in a light field.
