Title
* RNN Based Interference Mitigation for Automotive Radar
Highlight
This research aims to optimize the utilization of the 79 GHz frequency band by proposing a time-domain wideband interference suppression method using Recurrent Neural Networks (RNN), allowing multiple millimeter-wave FMCW radars to simultaneously use the same frequency band. Additionally, the proposed suppression method will be implemented in a chirp-sequence FMCW radar prototype developed in collaboration with a company, with the goal of practical application through demonstration experiments.
