Embodiment 1

[0028] Embodiment 1, this embodiment discloses a broadband array formation method for high-frequency precise suppression, including the following steps:

[0029] (1) Based on the high-frequency ionospheric propagation theory and the communication or suppression distance, the scanning range of the high-frequency broadband array is calculated, and then the normal angle of the broadband array is determined:

[0030] The reception of short-wave signals depends on the ionosphere, and the elevation angle of incoming waves is closely related to the state of the ionosphere. The ionospheric plane layers mainly include D layer, E layer, and F layer. The D layer mainly absorbs short-wave band signals; the E layer appears rapidly at sunrise and disappears rapidly at sunset, and its height is generally about 90-140km; The F layer is the layer where the ionosphere often exists and has the highest electron concentration. The height is above 140km. In summer, the F layer is divided into upper...

Abstract

The invention discloses a high-frequency precise-suppression broadband array forming method. The improvement lies in that the method comprises the following steps: calculating a high-frequency broadband array pitch plane scanning range according to a high-frequency ionized layer propagation theory and a communication or suppression distance, and further determining a broadband array plane normal angle; (2) determining a high-frequency oblique polarization non-similar broadband unit antenna structure and a layout mode; and (3) determining an edge positive mirror image structure according to theworking frequency of the high-frequency array: adding a parasitic reflector at the top of the array. The high-frequency precise-suppression broadband array forming method has a scientific research value and a military application prospect, a new technical route is provided for design and research of similar high-frequency broadband antenna arrays and the like, and powerful support is also provided for application of an ultra-wideband system.

Description

technical field [0001] The invention belongs to the research field of precision electromagnetic and communication interference, and in particular relates to a broadband array formation method and device for high-frequency precision suppression in this field. Background technique [0002] The high-frequency array antenna is composed of several antenna units, which transmit (or receive) at the same time with multiple antennas, and combine to form a high-gain, narrow beam. It can be used in broadcasting, communication, electronic warfare and other fields. It is a new hotspot in national defense construction and national defense research at home and abroad, and a new field of key electronic warfare development. For the communication or suppression of the target within the range of 2000-3000km, the antenna selection is logarithmic periodic antenna array (horizontal or vertical) and in-phase horizontal antenna (horizontal). At present, there is no suitable antenna array that meets...
