摘要

雷达传感器是日常交通中常见的设备，特别是用于驾驶员辅助和汽车安全系统。高传感器密度增加了干扰的可能性，特别是当传感器占用较大的雷达带宽时。许多电流传感器，如啁啾序列雷达，依赖于频率调制方案。正交频分复用(OFDM)是一种很有前途的雷达概念。本文研究了OFDM雷达对啁啾序列雷达的干扰效应。推导了潜在的干扰电平，并通过仿真评估了调制参数的影响。

Interference of chirp sequence radars by OFDM radars at 77 GHz

Radar sensors are common devices in daily traffic, especially for driver assistance and automotive safety systems. A high sensor density increases the probability of interferences, especially when the sensors occupy a large radar bandwidth. Many current sensors, e.g. chirp sequence radars, rely on frequency modulation schemes. A promising future radar concept applies orthogonal frequency division multiplexing (OFDM). This paper investigates the interference effect of an OFDM radar on a chirp sequence radar. Potential interference levels are derived and the influence of modulation parameters is evaluated with simulations.
