Description
Technical Field
The utility model relates to a radar jamming device field especially relates to a high-power continuous wave transmitting equipment of X wave band.
Background
Aiming at the increasing complex electromagnetic signal environment and the threats of radars of various current new systems, the current high and new technology is required to be utilized to accelerate and update the existing radar interference equipment, and the new technology and the new systems which may appear must be aimed, so that the new radar interference technology is discussed, and the radar interference equipment which is more effective is accelerated to be developed and equipped, so as to improve the overall fighting efficiency of radar countermeasure. The high-power continuous wave solid-state power amplifier is a core component of an electronic countermeasure and interference system. However, the output power of a single solid-state power device in the X-band is limited, which far cannot meet the requirement of high-power satellite communication, and the application of the solid-state transmitter in radar and electronic countermeasure is severely restricted. Due to the limitation of the current technological level, the output power of a single-tube solid-state power amplifier is limited, and in order to obtain larger power output, a power synthesis mode is needed to be adopted, so that a plurality of amplifiers are output in parallel to improve the output capacity; meanwhile, various radar devices also apply various anti-interference technologies, so that the interference and deception effects of the radar jammers of the conventional system are greatly reduced; therefore, in order to further improve the performance of the jammer, the radar jammers with the latest system all adopt the system of an active phased array; the development of a high-power solid-state transmitter with a limited volume is particularly important.
The X wave band is one of the main frequency bands of the current military electronic technology development, has better balance between air attenuation and resolution ratio, and is widely applied to the aspects of air-to-ground search radar, missile accurate guidance, remote sensing, secret communication, electronic countermeasure and testing technology and the like. The X wave band is also an object mainly aimed at by stealth technology, and is the absorption peak of the wave-absorbing material, which is the defect of the X wave band radar and the communication system. The method for making up the defect mainly relies on the improvement of power, and the improvement of system power means that the method has the advantages of larger action radius, stronger anti-interference capability, better communication quality and the like. As a key component of a microwave millimeter wave transmitting system, the output power of a power amplifier directly determines the action distance, the anti-interference capability and the communication quality of a transmitter. Compared with a vacuum tube transmitter, the solid-state transmitter has the advantages of low working voltage, high reliability, good maintainability, low whole life cycle cost, good maneuverability and the like, so that the solid-state transmitter is more and more widely applied to the fields of ground, vehicle-mounted, ship-mounted, airborne, satellite-mounted and the like. However, most solid-state transmitters currently used have a problem that the transmission power in a limited space is limited, which results in poor interference effect of the jammer.
