本文提出了一种利用直接序列扩频信号进行通信的新方法和雷达探测相结合的系统。这些信号受益于它们的属性，关于多个发射器之间的减少的干扰。这种干扰是由于现代车辆中集成了越来越多的雷达传感器以实现车辆周围环境的360度视图。为了更多地了解周围环境，我们的想法是通过连接车辆并在它们之间建立通信来获得更多信息。因此，77 GHz的雷达信号被调制以交换i。e.汽车之间的进入环境的安全信息。因此，这两个部分被集成到一个平台中，这降低了成本以及占用的空间。一个系统，这是能够这种设计方法，在MATLAB/Simulink环境中。传播参数由电磁场仿真器WinProp仿真，并反馈到Simulink仿真。该工作流程为联合传感通信提供了一个很有前途的仿真工具。最后的概念证明的传感和通信部分提出了一个典型的交通情况。
In this paper, a system that combines radar sensing and a new communication approach, using Direct-Sequence-Spread-Spectrum-signals, is presented. Those signals benefit from their attributes, regarding the reduced interference between multiple transmitters. This interference is caused by the fact that in modern vehicles more and more radar sensors are integrated to reach an 360 degree view of the vehicles’ surroundings. To gain more knowledge of the surrounding, the idea is to get further information by connecting vehicles and establishing a communication between them. Therefore, radar signals at 77 GHz are modulated to exchange i. e. safety information of the incoming surroundings between cars. In consequence, both parts are integrated into one platform, which reduces both costs as well as occupied place. A system, which is capable of this design approach, is presented in MATLAB/Simulink environment. The propagation parameters are simulated by an electromagnetic field simulator WinProp and are fed back into the Simulink simulation. This workflow provides a promising simulation tool for joint sensing-communications. The final proof of concept of the sensing and communication part is presented for a typical traffic situation.
