516 THE RECEIVING SYSTEM—INDICATORS [SEC. 13.11 isthe desired signal. Since there aretwonulls perrevolution, the synchro must be geared up by?a ratio equal to half the number of markers. In the figure the null lS used as a switching signal for an oscillator of frequency approximately one megacycle per second. The train of pulses is ‘‘ rectified” by the cathode-ray tube, so that 4.5kclsec oscdlator II II — Scansynchro Controlsynchro AY-101 AY-101 I Ampl!fler _ Detector , T +300V &6sr47 .—-- ‘F * 100k WA- --- 3 r Im M f ?5k $150k 6SN7 --- 0,01 300k Pulsedoscillator +150V 4 +3 47k ~r --- 0.0001 IL L 1 6SN7 FIG. 13.34 .—Synchro null indices. the marker appears as a row of dots which merge except on fairly fast sweeps. An oscillation of this sort is preferable to a simple rectangular pulse if the signals are to be passed through mixing or other circuits whose low-frequency response is not as good as demanded by the very long (as much as ~ see) marker pulse. Movable Electronic Angle Indices.-The methods of producing fixed electronic angle indices can be extended to provide movable ones. This can most easily be done, with the synchro method of Fig. 13.34, bv Usiw
SEC. 13.11] ANGLE INDICES 517 the second synchro to introduce the dilTerential setting. The two nulls will result in two signal markers 180° apart. If this is undesirable one of them can be removed by a method involving the use of a multiphase rotor in the second synchro. A second modulation envelope, 90° out of phase with the first, is obtained and used to blank one of the markers (see Fig. 4.5, Vol. 22). The production of a movable index by the contactor or photocell method requires that the differential setting be made mechanically. This method is seldom used unless the indicator contains a mechanical repetition of the scanner motion. Movable electronic indices appear on the indicator only when the cathode-ray beam is on a particular part of the tube face. To set an index on an echo, it is essential to be able to observe the results of moving the index. If the scan is rapid, the o~erator has freauent chances to do so, but if it is slow he cannot correct an error for several seconds. This is not too serious in the case of the movable range marker, because it appears at all azimuths and can be’ 6steered” in the proper direction as it approaches the persistent echo remaining from the previous scan. An angle index, on the other hand, if formed by the methods of @w ),1 1 Data transmitter * Operator’s control Display circuits FIG. 13.35.—Substitution method for movable angle index. the preceding paragraph will “flash up” only as the scanner passes by. The operator has no chance to make a correction before the next scan, and even then the correction must be an educated guess. It is very difficult to make accurate settings within the space of a few scans, especially if there is relative motion between radar set and target. 1 It is, therefore, essential on slow scans to use some other method. For all displays except rotating-coil PPI’s, the so-called “substitution” method illustrated in Fig. 13.35 can be used. From time to time control of the display is switched from the regular angle data transmitter to one that can be set by the operator. During these intervals the direction taken by the range sweep is determined by the setting of the “ substitution” transmitter and is thus under the control of the operator. The switching may be made to occur automatically on a certain fraction of the range sweep cycles equally distributed throughout the scan (which requires rapid electronic switching), or it may occur continuous y over an I The problem is greatly simplified if aided tracking is used—that is, if come am%of computer moves the index in accordance with the relative motion, using knowledge acquired by making the best settings possible in the past.
