Problems solved by technology

[0003] The actual application of the transmitting antenna in the existing high-power countermeasure system using space power combining technology is generally 4 channels or 6 channels, the number of space combining channels is small, and the output power of a single channel is generally lower than 400W, resulting in a small overall output continuous wave power , it is difficult to meet the requirements of megawatt-level power output; in addition, in terms of beam pointing and tracking design, it is basically a single mechanical scanning tracking or electronically controlled scanning tracking. Combined application, reduce engineering design difficulty in special application environment, improve system pointing and tracking accuracy, etc.

Abstract

The invention discloses an offset feed electric control fusion antenna and system. The antenna comprises an antenna bracket, a multi-channel steering flange, a servo turntable, a counterweight structure, a multi-channel flexible waveguide array, a bent waveguide array, a parabolic reflection cylindrical surface and a feed source horn array; a feed source horn array is longitudinally arranged on the focal point of the parabolic reflection cylindrical surface, and the feed source horn array and the parabolic reflection cylindrical surface are combined together through the antenna bracket to forma whole; one end of the antenna bracket is arranged on one port of the multi-channel steering flange; one end of the multi-channel flexible waveguide array is mounted at the input port of the multi-channel steering flange; one end of the bent waveguide array is connected with the output port of the multi-channel steering flange, and the other end is connected with the input port of the feed source horn array; multi-path high-power signals are transmitted to the feed source horn array through the multi-path flexible waveguide array, the multi-channel steering flange and the bent waveguide array; after spatial power synthesis is conducted on the signals through the feed source horn array, the signals are incident on the parabolic reflection cylindrical surface and transmitted to a specifictarget area.

Description

technical field [0001] The invention relates to the technical field of transmitting antennas in high-power countermeasure systems, in particular to a bias-feed electronically controlled fusion antenna and a system. Background technique [0002] The transmitting antennas used in modern high-power countermeasure systems generally include horn antennas, parabolic antennas, flat panel array antennas, cylindrical omnidirectional antennas, etc. environment), these conventional antennas will not be able to meet the system requirements, especially when the system needs to achieve a continuous wave output power of the order of megawatts, due to the limitation of the withstand power of various microwave devices, the design idea of ​​single feed and conventional array antenna It can no longer meet the requirements, and it is also difficult to meet the scanning work requirements in the azimuth and elevation directions of the beam. Therefore, it is necessary to adopt a multi-channel hig...
