摘要： A sweep generator for a displaced-center sector-scan display of a radar system, in which the inductance of the cathode ray tube display device cooperates with a storage capacitor for directly generating a bipolar sweep current waveform utilized by the control yoke. A centering gate responsive to the radar timing, energizes the winding to start the sweep from a filter capacitor of the power supply. During a first polarity portion of the sweep the energized winding is storingly discharged into the capacitor and during the oppositely-polarized second portion of the sweep, a sweep gate allows discharge of the capacitor back into the winding. The winding energy is then discharged at the end of the sweep back into the filter capacitor of the power supply, whereby a very low-power source may be utilized for energizing the sweep generator.

摘要： An electromagnetic deflection system to provide a low-cost, depressed-center CRT display for a sector scanning sensor. An auxiliary coil (usually a ring) is wound about a cathode ray tube, axially spaced intermediate the conventional deflection yoke and the display face of the CRT, and oriented relative to the longitudinal axis of the tube to provide a resultant magnetic vector which is mutually angled relative to such longitudinal axis. The deflection system can be driven by conventional low cost flyback deflection circuits producing sawtooth deflection currents. For example, in a display for an azimuthally scanning radar, the radar range sweep generator frequency output need be applied only to the vertical deflection winding of the conventional deflection yoke, while the radar azimuth scan frequency is applied either to the auxiliary coil alone or to the auxiliary coil and the horizontal deflection winding of the conventional deflection yoke in series.
