Definitions

  • Ross ABSTRACT A plurality of transmitting and/or receiving radiators made operational in a predetermined sequence, confront a focusing assembly which includes an array of controllable phase shifters for converting planar waves into spherical waves or vice versa, the phase shifts introduced by this array being periodically altered under the control of a timer to center the spherical wave fronts on one side of the array successively upon the several radiators whenever the latter are made operational.
  • FIG. 6 illustrates a preferred construction of each of the individual phase-shifter units 71 through 75in FIG. 5. It comprises a hybrid junction or magic-T having an input leg 709, an output leg 712 and the two unequal side legs 710 and 711, having shorted terminations 715 and 716. Diodes 713 and 714 are connected across the sidewalls of the respective side legs 710 and 711, at predetermined distances from their shorted ends 715 and 716. The diodes are connected in parallel 1 between the control line (1111 to 105, FIG. associated with the particular phase-shifter unit (71 to 75) and a common blessing-voltage source V through a resistor.
  • the diodes 713 and 714 are both nonconductive, so that the effective short-circuited lengths of the side legs 7111 and 711 of the magic-T are the full lengths of said legs, as indicated at L1 and L2.
  • the positions pf the diodes 713 and 714 are so predetermined that when these diodes are conductive (control signal applied), the split incident wave travelling down the side legs 710 and 711 and reflected from the shorted terminations represented by the diodes 713 and 714 reappears at the junction with the output leg (say 712) as two reflected waves cophasal with each other but difi ering in phase by a prescribed angular amount from the phase of the incident wave.
  • Analogous schemes are used to designate the radiating elements of the forward array (hundreds digit 5) and also to designate the phase shifters interconnecting corresponding elements of both side arrays (hundreds digit 6), as well as the control lines connected to said phase shifters (hundreds digit 10).
  • FIG. 7 shows an additional register 860 having the value 18 It preset therein, and having its outputs connected to inputs of register 858 by way of AND gates 862,. whose enabling inputs are connected in parallel to the output of monostable circuit 822.
  • the transmitters 91 9N may all be operated in coherent relationship so that the unit pulses transmitted by the transmitter array will then be practically equivalent to asingle pulse of greatly increased duration.
  • the effective duration of the resulting protracted pulse is seen to be substantially equivalent to NT, since the idle intervening periods AT can be made extremely short when using digital switching techniques of the general character disclosed herein.
