Abstract

The invention relates to the technical field of electronic countermeasures radio frequency stimulation, and discloses electronic countermeasures radio frequency artificial antenna array equipment and a feed control method. The equipment adopted in the method is connected with the input end of a power combiner through a plurality of feed control circuits connected with radio frequency signals, and a plurality of channels of the first part of the output end of the power combiner are connected with the input end of a polarization control circuit through feeder lines. A plurality of channels of the second part of the output end of the power combiner are correspondingly connected with the input end of the polarization control circuit through last-stage amplification control circuit channels. The output end of the polarization control circuit is connected with a triad radio frequency artificial antenna array. The method that high-output-power antenna units and low-output-power antenna units are arranged alternately is adopted, and the aims that a simulation system can meet large-caliber antenna equipment with high radio frequency signal receiving capacity, and the experiment of small-caliber antenna equipment weak in radio frequency signal receiving capacity to radio frequency simulation can be considered are achieved, and the electronic countermeasures radio frequency artificial antenna array equipment and the feed control method have the advantages of being high in reliability and flexible in system work configuration and transformation. The structure is simple, and cost is low.

Description

[0001] technical field [0002] The invention relates to the technical field of electronic countermeasure radio frequency simulation, in particular to an electronic countermeasure radio frequency simulation antenna array device and a feeding control method in the realization of radio frequency simulation antenna array, which is applicable to a general electronic countermeasure radio frequency simulation test system. Background technique [0003] At present, the triad antenna: the target signal simulated by the simulation system is the synthesized signal obtained by the radiation of three adjacent units of the antenna array. These three units are generally arranged in an equilateral triangle to form an antenna sub-array, which is a triad set of antennas. [0004] Radio frequency simulation antenna array: a group of antennas used to transmit electromagnetic signals such as radar echo signals, interference signals, and clutter in radio frequency simulation tests, so as to simul...
