Interference Mitigation in Automotive Radars 

In the case of automotive radar sensors that monitor the environment, one of the current challenges is the problem of mutual interference, which is recently getting more attention due to the increase of the number of radar systems used in traffic. The higher density of radar sensors in the same area leads to the occurrence of interference, which decreases the detection capabilities. In the state-of-the-art there are several radio-frequency interference (RFI) mitigation algorithms that usually envisage only one interference source. Most of these algorithms are assessed by simulations, and only a few of them have been implemented in real automotive radars. The results of this project will deliver a set of experimental results for a novel RFI mitigation algorithm in several real-life configurations with multiple interferers.


The goal of the Interference Mitigation in Automotive Radars project is to develop, implement and test in a relevant environment an RFI mitigation method for automotive radars. The main technical objectives that will be followed during the project are:

  1. To develop an RFI mitigation algorithm (for an FMCW radar architecture) that has a reasonable computation/implementation effort.
  2. To implement the developed algorithm on a microcontroller (or digital signal processor) that can process in real time the signals acquired by the radar.
  3. To assess the interference mitigation performance in various scenarios with multiple FMCW radars that operate simultaneously.
