Abstract

The invention provides a shaping radome and a radar device. The shaping radome comprises a dielectric layer and a shaping layer; the shaping layer is arranged under the dielectric layer, the shaping layer is used for shaping a plurality of antennas, and the antennas are arranged under the shaping radome; the shaping layer is provided with a plurality of strip-shaped media which are arranged in a non-uniform manner, and the strip-shaped media are used for changing the dielectric constant of the shaping radome, so that the dielectric constant of the shaping radome tends to 1. According to the shaping radome, refraction influence of the shaping radome on radar electromagnetic waves can be reduced, and the situation that the directional diagram gain of the wide-beam antenna is greatly reducedalong with the increase of the angle is avoided, so that the effect that the radiation directional diagram of the wide-beam antenna is close to that without the radome is achieved.

Description

technical field [0001] The present application relates to the technical field of millimeter wave antennas, in particular to a shaped radome and a radar device. Background technique [0002] With the development of large-scale integrated circuit technology, the currently used automotive millimeter-wave anti-collision radar system is highly integrated. Automotive millimeter-wave radar usually only includes antennas and several radio frequency transceiver and signal processing monolithic integrated circuit (MMIC) chips. In this way, the antenna becomes one of the key design components for the effective operation of the automotive millimeter-wave radar, and at the same time, it also becomes the key to whether the millimeter-wave automotive radar can win the market. [0003] At present, the mainstream 77GHz frequency band millimeter-wave radar is mainly divided into long-range radar (LRR), medium-range radar (MRR) and short-range radar (SRR) according to the requirements of diffe...
