Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0059] An embodiment of the present invention provides a multi-band airborne radar antenna, which includes:

[0060] The first-band antenna array and module components are fixed on an antenna support structure;

[0061] The second band antenna array and module components are fixed on the antenna support structure; and

[0062] The N-band antenna front and module components are fixed on the antenna support structure;

[0063] Wherein, N≥3, and the first band, the second band and the Nth band are different from each other.

[0064] In some embodiments, the first band, the second band and the Nth band are different bands, such as L band, S band, C band, X band, Ku band, K band, Ka band, etc.

[0065] In this embodiment, a...

Abstract

The invention discloses a multiband airborne radar antenna, which comprises a first waveband antenna array and a module assembly, which are fixed on an antenna support frame structure; a second waveband antenna array plane and a module assembly, which are fixed on the antenna support frame structure; and an Nth waveband antenna array plane and a module assembly, which are fixed on the antenna support frame structure, wherein N is greater than or equal to 3, and the first waveband, the second waveband and the Nth waveband are different. According to the multi-band airborne radar antenna provided by the invention, a plurality of waveband radar antennas are integrated in one airborne radar antenna structure, the layout is reasonable, the assembly is compact, rapid disassembly and assembly canbe realized, and the heat dissipation requirement of a high-integration assembly can be met.

Description

technical field [0001] The invention relates to the technical field of radar communication, in particular to a multi-band airborne radar antenna. Background technique [0002] At present, airborne radar has become an important means of surveillance in the fields of military and civilian remote sensing detection and disaster monitoring. Radars of different bands have different imaging characteristics of the ground, and at the same time, the details of the ground objects are also different. In the fields of natural disaster monitoring and remote sensing imaging, it is often necessary to use radars of different bands to fly multiple times on the same plot to obtain ground features. different characteristics of objects. At present, most airborne radars are equipped with a radar antenna of one band, and there is no design for integrating multiple band radars into one radar antenna structure. Contents of the invention [0003] In order to solve the above shortcomings, the pres...
