Abstract

The invention discloses a broadband array multi-beam forming method, which relates to the simultaneous interference technology for multiple communication targets of the enemy in the field of communication. The present invention adopts a 96-element antenna array with a frequency coverage of 600-3000MHz, uses digital intermediate frequency amplitude and phase calibration technology, and can generate 8 independent and controllable beams at the same time in the 50MHz instantaneous frequency band; the interference beam is controlled by digital means at the intermediate frequency Realization, beam pointing and side lobes are flexible and controllable; the invention uses a system calibration receiver to realize online real-time calibration of system beam forming, and enhances the engineering practicability of the system. The equipment manufactured by the invention has the characteristics of flexible operation, reliable performance, high-efficiency interference and the like. It is especially suitable for jamming important communication targets in enemy theaters, and can be applied to platforms such as airborne, shipborne, and vehicle-mounted.

Description

technical field [0001] The invention relates to a broadband array multi-beam forming method in the communication field, which is especially suitable for interfering with key communication nodes in an enemy's combat zone, and can be applied to various combat platforms such as airborne, shipborne, and vehicle-mounted. Background technique [0002] From the perspective of communication interference, the (equivalent) radiated power and airspace coverage of the jammer are one of the important factors affecting the effectiveness of interference. In practical tactical applications, the storage space of confrontation targets is mostly discretely distributed (even sparsely distributed). Therefore, it can be combined with reconnaissance and direction finding, and the precise directional jamming method can be adopted. In this way, under the premise of a given total output power of the power amplifier, while satisfying the airspace coverage, the main power can be concentrated to carry ...
