dc.description.abstract | The automotive radar microwave antenna circuit board is a part of the automotive active radar detection module supply chain, and is located in the tier 2 supply chain, is also a key component of automotive microwave radar module assembly, accounting for the entire assembly cost of 10- 20% material cost. The automotive radar microwave hardware module includes a transmitter, the function of which is to generate an RF signal; the receiver converts the RF signal tube into a low frequency signal; the processor converts the signal into a distance, a speed, and an angle through operation; and the antenna, Responsible for converting electrical energy into electromagnetic waves. The higher the frequency band used by the radar, the shorter the wavelength, and the higher the resolution speed and accuracy. This is an important feature of microwave radar.
In order to effectively reduce automobile driving accidents, in recent years, the auto-driving function of automobiles has been paid more and more attention and welcomed by consumers. The application requirements of automotive radar electronic products are also fermented quickly in in the supply chain, but due to rapid demand. Production and assembly of the entire industry may not immediately achieve optimal design and optimization of production conditions. Therefore, it is necessary to ensure the quality level through testing and measuring the electronic performance. This inevitably increases the cost of many learning curves. Therefore, it is necessary to identify the factors that will lower the manufacturing and quality variation, and then obtain stable quality and improve the industrial interest. The most important target.
This paper focuses on the optimization design of the microwave antenna of the automotive radar module. Firstly, it analyzes the main factors through the existing controllable key characteristic items, measurement data and microwave final performance analysis, and then applies the experimental design method to this factor. Find out the optimal production conditions by the impact of production.
However, the most important factor affecting the performance of automotive radar is the quality characteristic structure design of the antenna. In order to explore the optimal manufacturing of automotive radar antennas and methods, this study first establishes and analyzes the research model and combines the Taguchi method to find the optimal production design combination to effectively improve the efficiency and quality of the overall automotive radar antenna circuit board.
