Title: Improvements in or relating to radar display apparatus
Inventor: MATTHEWS ROBERT
IPC: G01S13/538
Filed: 1954-10-13
Abstract: 818,475. Pulse radar. DECCA RECORD CO. Ltd. Oct. 10, 1955, No. 29561/54. Class 40(7). In a pulse radar comprising a scanning aerial, a display C.R.T. and a storage C.R.T. having separate reading and writing beams, the display of images corresponding to stationary targets is prevented by delaying the received echo signals by a fraction of the aerial scan period, modulating the reading beam of the storage tube with said delayed signals and modulating the display tube in accordance with the difference between the undelayed echo signals and the reading output from the storage tube, the scanning of the display tube and the reading beam being coplanal and the writing beam scan being delayed relative to the reading beam scan by said fractional aerial scan period. The display tube may be deflection modulated or intensity modulated, e.g. P.P.I. or type B. In the embodiment described, a P.P.I: display is produced by tube 22 and the reading and writing beams of storage tube 60 are scanned in a corresponding manner, the amplitudes of the X and Y time-base generators 18, 19; 52, 53 and 54, 55 being controlled by a magslip 14 ganged to the rotating aerial 12. The display and reading beam time-bases 18, 19; 52, 53 are triggered by the output from a gate pulse generator 50 which is triggered by the direct pulse from the transmitter 10 as received at 13 and selected by limiter 51. The output from receiver 13 is also applied to a combining circuit 71 and through a delay 65 and amplifier 66 to modulate the writing beam of tube 60 and to trigger the writing time-bases 54, 55 so that the writing signals are retarded slightly, e.g. 10-30 Á-secs, relative to the reading signals. If adjacent traces on the storage tube do not overlap, the reading beam will read out the signals stored during the previous rotation period of the aerial and these signals, after adjustable amplification at 70, are subtracted from the undelayed echo signals in circuit 71 and the resultant signal is applied to the display tube 22. If adjacent traces on the storage tube overlap, the arrangement will tend to cancel signals stored on the previous trace. Preferably, the storage tube is such that the reading beam erases the stored signals but a separate erasing circuit may be provided. Specifications 679,722, 679,723 and 818,477 are referred to.
