出于开发自主车辆系统的各种组件的硬件，能源和频谱资源相结合的需要，我们提出了一个联合FMCW雷达和通信（RadCom）系统。所提出的波形包括调频啁啾，用于雷达和通信。目标检测是使用基于FFT的过程来完成的。与传统的FMCW雷达接收器相比，我们已经考虑了短的线性调频脉冲持续时间来增加数据速率，从而导致混合后具有不可忽略的频率分量的具有挑战性的场景，对应于连续线性调频脉冲符号之间的过渡。对于这种情况下，我们得到了一个封闭的形式的分析解决方案的检测和虚警概率，并模拟了使用非相干接收机的通信系统的性能。最后，仿真结果表明所提出的联合RadCom系统的目标检测和通信符号解码的性能。
Motivated by the need of combining hardware, energy and spectrum resources of various components towards developing autonomous vehicular systems, we propose a joint FMCW radar and communication (RadCom) system. The proposed waveform consists of frequency-modulated chirps, used for both radar and communications. Target detection is done using an FFT-based procedure. In contrast to the conventional FMCW-radar receiver, we have considered a short chirp duration to increase the data rate, resulting in a challenging scenario with non-negligible frequency components after mixing, corresponding to the transition between successive chirp symbols. For this scenario we obtained a closed-form analytic solution for detection and false-alarm probabilities, and simulated the communication system performance using a non-coherent receiver. Finally, simulation results are presented to demonstrate the performance of target detection and communication symbol decoding for the proposed joint RadCom system.
