This method requires additional installation holes in the bumper, which has greater safety for the bumper structure. Doubts, and as a result, due to space constraints, in-vehicle radars generally can only use PCB microstrip antennas (microstrip antennas) to directly send and receive radio waves, but cannot use parabolic antennas with high directivity to increase the gain. Therefore, the radar’s The angle and resolution are not easy to improve. At the same time, the lack of antenna aperture limits the maximum distance that the radar can detect. Although some inventors have installed millimeter-wave radars in car lights, please refer to US Patent No. US8803728B2 "Millimeter wave radar-equipped" headlamp", which discloses a headlamp equipped with a millimeter wave radar, which is mainly composed of a lighting device unit, a frame and a millimeter wave radar, and the lighting device unit may include a projection lens, a light source, and a millimeter wave radar. The reflector and a hood, the projection lens is used to transmit the light generated by the light source out of the car lamp, the light source is used to generate an illuminating light source, and the reflector is used to reflect the light generated by the light Reflected to the outside of the car lights, the hood is used to block part of the reflected light from the reflector. In addition, the millimeter wave radar may include an antenna module, a millimeter waveguide tube, a millimeter wave reflector, and a control module. : The antenna module is used to receive millimeter waves, the millimeter waveguide tube is used to transmit millimeter waves, and the millimeter wave mirror can reflect the millimeter waves generated by the millimeter waveguide tube to the outside of the projection lens. The control module is used to control the antenna module; accordingly, this U.S. patent proposes an invention in which a millimeter wave radar is installed in the headlight of a vehicle; there are other references as follows:

然而，第US8803728B2号美国专利所提出的配备有毫米波雷达的前照灯，其毫米波雷达探测范围极为窄小，若要增加毫米波雷达的探测范围，则必须增加毫米波雷达的设置数量，若增加毫米波雷达数量，所增设的毫米波雷达面积势必增加，这将遮挡到光源的照射路径，提升毫米波雷达的探测范围，却也牺牲掉照明光线的照射范围，对于车辆而言更加危险，据此，如何将毫米波雷达结合在车灯内部，并且不会干涉到照明光源，同时能保证雷达具备较高的远场指向性增益与角分辨率，此乃待需解决的问题。However, the headlamp equipped with millimeter-wave radar proposed in US Patent No. US8803728B2 has a very narrow detection range of millimeter-wave radar. If the detection range of millimeter-wave radar is to be increased, the number of millimeter-wave radars must be increased. If the number of millimeter wave radars is increased, the area of the millimeter wave radars added will inevitably increase, which will block the illumination path of the light source and increase the detection range of the millimeter wave radar, but it also sacrifices the illumination range of the illumination light, which is more dangerous for vehicles According to this, how to integrate the millimeter wave radar inside the car lights without interfering with the illuminating light source, while ensuring that the radar has a higher far-field directivity gain and angular resolution, is a problem to be solved.
另，车载毫米波雷达一般采用相位控制数组形式的收发方式，以多组天线形成基线，控制发射端的波束方向，但这样的***中，其 单一天线的指向性增益通常较低，无法形成具备完整指向性的波束，因此可能存在车辆间不同发射源互相干扰的问题，而接收端则因为合成波束的指向性限制，即便以较复杂的算法，亦只能在一定程度内减少干扰，故在有限的信噪比下，视角内探测多个目标的信号之间容易产生混淆，同时在有限的发射功率下，可探测的距离范围因为波束分散而被限制。In addition, vehicle-mounted millimeter-wave radars generally use phase control arrays to form a base line to control the beam direction of the transmitting end. However, in such a system, the directivity gain of a single antenna is usually low, and it is not possible to form a complete antenna. Because of the directional beam, there may be a problem of mutual interference between different emission sources between vehicles. However, due to the directional limitation of the composite beam, the receiving end can only reduce the interference to a certain extent even with a more complex algorithm, so it is limited. With a high signal-to-noise ratio, it is easy to cause confusion between signals that detect multiple targets within the viewing angle. At the same time, with a limited transmit power, the detectable distance range is limited due to beam dispersion.

请再搭配参阅图3，波束过滤模块105由透光材料制成，使可见光可以自由穿透过波束过滤模块105，其可以为玻璃材料、透明陶瓷、亚克力等透明非导体材料，皆可以实施，再者，波束过滤模块105另布设有一波反射单元1051，所述的波反射单元1051为1毫米以下的导体金属结构，其可以为导体线数组或导体织网，透过间隔小于1毫米的导体线，使波反射单元1051可以完整的反射电磁波，并且同时可以提供光线穿透过去。Please refer to FIG. 3 again.

Line, so that the wave reflection unit 1051 can completely reflect electromagnetic waves, and at the same time can provide light to penetrate past.
请再参阅图2，反射镜103表面组设有一毫米波雷达模块106，其中，所述的毫米波雷达模块106由焦平面天线数组组成，所述的焦平面天线包含有至少一微波发射单元和至少一微波接收单元，毫米波雷达模块106透过金属导体构成的反射镜103将电磁波的能量聚焦于特定方向，达到对远处物体精准的探测，据此，毫米波雷达模块106具有较高的指向性增益，对于特定方向上的物体，能集中更多射频功率进行探测，亦大幅提高了雷达的信噪比，所以能够探测更远的物体，又，毫米波雷达模块106将多组焦平面天线数组(微波发射单元和微波接收单元)设置于焦距平面上的多个不同的位置，可以透过同一组反射镜103的反射面，同时探测多个方向的目标，而每个微波发射单元和微波接收单元可以独立的开关或是调制发射功率，可在最大程度上减少对目标空间的电磁干扰，避免其他的雷达***发生误判的状况，又，所述的焦平面天线数组还可以相位数组排列于反射镜103，焦平面数组可以集中波束的角度分辨率。Please refer to FIG. 2 again, the surface assembly of the reflector 103 is provided with a millimeter wave radar module 106, wherein the millimeter wave radar module 106 is composed of a focal plane antenna array, and the focal plane antenna includes at least one microwave transmitting unit and At least one microwave receiving unit, the millimeter wave radar module 106 focuses the energy of electromagnetic waves in a specific direction through a reflector 103 made of a metal conductor, so as to achieve accurate detection of distant objects. According to this, the millimeter wave radar module 106 has a higher Directivity gain, for objects in a specific direction, can concentrate more radio frequency power for detection, and also greatly improve the signal-to-noise ratio of the radar, so it can detect farther objects. In addition, the millimeter wave radar module 106 integrates multiple sets of focal planes. The antenna arrays (microwave transmitting unit and microwave receiving unit) are arranged at multiple different positions on the focal plane, and can pass through the reflecting surface of the same set of mirrors 103 to detect targets in multiple directions at the same time, and each microwave transmitting unit and The microwave receiving unit can independently switch or modulate the transmission power, which can minimize the electromagnetic interference to the target space and avoid the misjudgment of other radar systems. In addition, the focal plane antenna array can also be a phase array Arranged on the mirror 103, the focal plane array can concentrate the angular resolution of the beam.
另，由于未来车载照明可能以多组LED形成数组为主流，故在本发明的实施例中，基于在反射镜103上的焦平面数组可以集中波束的基础上，多个车用灯具***10可在空间中形成特定数组分布，并设定焦平面数组中收发机(焦平面天线)的信号源同步，因此每个反 射镜103上焦平面数组的某个元素(焦平面天线)，和其它反射镜上焦平面数组的波束方向相同的对应元素可再组成一相位数组，如此一来，所述的相位数组可在每个波束中更细化原先由焦平面数组所提供的角分辨率，其中，本实施例的相位数组的每个波束可以提供5～10度独立视角，而相位数组可以提供<1度的角分辨率，两者融合(通过数字波束合成)可以达到广视域图像及高分辨率适应性的成像雷达。In addition, since the future vehicle lighting may use multiple groups of LEDs to form an array as the mainstream, in the embodiment of the present invention, based on the focal plane array on the reflector 103 that can concentrate the beams, multiple vehicle lighting systems 10 can be used. Form a specific array distribution in space, and set the signal source of the transceiver (focal plane antenna) in the focal plane array to be synchronized, so a certain element (focal plane antenna) of the focal plane array on each mirror 103, and other reflections Corresponding elements with the same beam direction of the focal plane array on the mirror can then form a phase array. In this way, the phase array can refine the angular resolution originally provided by the focal plane array in each beam, where Each beam of the phase array of this embodiment can provide independent viewing angles of 5-10 degrees, while the phase array can provide angular resolution of <1 degree. The fusion of the two (through digital beam synthesis) can achieve wide-view images and high-resolution images. Resolution adaptable imaging radar.

After passing through the beam filter module 105, it is reflected by the reflector 103 and irradiated outside the lampshade 102 to complete the light irradiation path. When the optical module 104 is a light emitting diode, the optical module 104 can be reflected by the reflector 103. Increase the illumination range of the illumination light L1, and the reflective surface of the reflector 103 can be formed with a diffuse reflection structure, so that after the illumination light L1 is reflected by the reflector 103, the illuminating light L1 irradiated can be more uniform and soft; When the system 10 provides millimeter wave radar detection, after the control module 107 drives the millimeter wave radar module 106, the millimeter wave radar module 106 transmits a millimeter wave signal L2 through the focal plane antenna array, and transmits the millimeter wave signal L2 to the beam filter module 105 .
