S-band megawatt dual-unit hot standby transmitter and control method thereof

Abstract

The invention discloses an S-band megawatt dual-unit hot standby transmitter and a control method thereof. The S-band megawatt dual-unit hot standby transmitter comprises two high-power transmitters A and B, a waveguide switch with four ports, a microwave load, antennae and feeder wires, wherein four ports divided into two groups are formed in the waveguide switch and form a cross shape, every two of the four ports are opposite to each other, and the opposite ports are not communicated; output waveguides of the transmitters A and B are connected to one group of opposite ports of the waveguide switch respectively, the microwave load and the feed wires are connected to the other group of opposite ports of the waveguide switch, and output of each transmitter gets to the antennae through the feed wires; the waveguide switch comprises a stator and a rotor, the stator is a framework of the waveguide switch, the four ports are formed in the stator, and the rotor is controlled by a micromotor of the waveguide switch to rotate, and accordingly, the antennae are connected with one of the transmitters A and B. The invention further discloses of the control method of the S-band megawatt dual-unit hot standby transmitter.

Description

technical field [0001] The invention relates to a transmitter in the field of radar and electronic countermeasures and a control method thereof, in particular to an S-band megawatt-level dual-machine hot backup transmitter and a control method thereof. Background technique [0002] With the increasing demand for homeland air defense intelligence and the development of high-power electronic countermeasure technology, higher requirements are put forward for the reliability and long-term working ability of high-power national defense electronic equipment such as radar and electronic countermeasure, especially in special places such as mountains and islands. station, the demand for the reliability and long-term working ability of these equipment is more urgent. [0003] On the other hand, since the power devices in high-power transmitters need to handle large power, their reliability is limited, and gradually become the bottleneck of the reliability of these equipment, especiall...

Problems solved by technology

The so-called cold backup is: the backup parts or transmitters do not work normally, and are not in the preheating state. Once the working transmitter or its parts fail during work, it needs to be shut down and replaced with a backup transmitter. Or components, the replacement process not only requires shutdown, but also the disassembly and assembly process. If the transmitter is replaced, it often involves the disassembly, assembly, and debugging of the waveguide and water cooling system, and the preheating process when restarting It is also inevitable that replacing spare parts is time-consuming, and even the process of replacing spare parts will have a greater impact on combat readiness tasks
