GATE TRANSMITTER FOR LONG-RANGE RADAR SYSTEM Russian patent published in 1997 - IPC

FIELD: radio engineering, in particular, transmitters of long-range pulse- phase radar systems. SUBSTANCE: device has two hot-cathode tube oscillators 1, 2, U-shaped C-L-C circuit 3, communication induct coil 4, transmitting antenna 5. Each hot-cathode tube oscillator has hot-cathode tube 6, power supply 7, cut-off diode 8, charging choke 9, discharge capacitor 10, load parallel L-C circuit 11, which has serial circuit of inductance coil 12 and capacitor 13. In addition circuit 11 has discharge choke 14 and communication capacitor 15. U-shaped C-L-C circuit 3 has inductance coil 16, capacitors 17 and 18, matching capacitor 19, feeder line 20 and U-shaped C-L-C correction circuit 21, which has inductance coil 22 and capacitors 23 and 24. Inductance coil 16 and capacitors 17 and 18 are connected to provide U-shaped C-L-C circuit 3. Described gate transmitter provides possibility to generate and emit high-frequency filling radio pulses of given shape with given initial phase and to provide relative movement of transmitting antenna and U-shaped C-L-C circuit. EFFECT: increased functional capabilities. 6 dwg
