Embodiment Construction

[0038] The ordinal numbers used in the present invention, such as words such as "first", "second", and the corresponding components, do not include and represent that the component has any previous ordinal numbers, nor does it represent that a component is related to another component. The sequence of components, or the sequence of manufacturing methods, these ordinal numbers are used only to clearly distinguish one part with a certain designation from another part with the same designation.

[0039] The inventive concept of the present invention is to provide a radar antenna, which can detect the high-resolution requirements of highways.

[0040] The present invention provides a radar antenna, including a transmitting antenna assembly and a receiving antenna assembly, wherein,

[0041] The transmitting antenna assembly includes: a first upper radiating arm, a first lower radiating arm and a first impedance converter; the first upper radiating arm has two ends, and the end wit...

Abstract

The invention discloses an ultra-wideband radar antenna, which comprises a transmitting antenna module and a receiving antenna module, wherein the transmitting antenna module comprises a first upper radiation arm, a first lower radiation arm and a first impedance transformer; the receiving antenna module comprises a second upper radiation arm, a second lower radiation arm and the first impedance transformer, wherein the transmitting antenna and the receiving antenna have the same impedance transformer structure. The ultra-wideband radar antenna adopts special curves to form the antenna radiation arms and integrates the impedance transformer and the antennas together, the overall dimension of the antenna is smaller and the antenna has good wideband characteristic.

Description

technical field [0001] The present invention relates to the technical field of radar in the electronic industry, in particular to a radar antenna and a radar including the radar antenna. Background technique [0002] Ultra-wideband radar technology usually adopts a carrier-free pulse system to obtain high-resolution imaging through the characteristics of ultra-wideband. In the fields of road disease and track detection, UWB radar has the characteristics of fast, efficient, non-invasive detection, etc., and has developed rapidly in recent decades. Expressway construction not only benefits people's livelihood, but also plays an important role in promoting the national economy. For highway pavement stratification, road quality detection, etc., air-coupled ultra-wideband ground penetrating radar has broad application prospects. [0003] As the front-end sensor of the radar, the antenna is responsible for converting electrical signals into electromagnetic waves and radiating th...
