Estimating the Magnitude and Phase of Automotive Radar Signals under Multiple Interference Sources with Fully Convolutional Networks

1 code implementation11 Aug 2020 Nicolae-Cătălin Ristea, Andrei Anghel, Radu Tudor Ionescu

In order to train our network in a real-world scenario, we introduce a new data set of realistic automotive radar signals with multiple targets and multiple interferers.

Fully Convolutional Neural Networks for Automotive Radar Interference Mitigation

1 code implementation21 Jul 2020 Nicolae-Cătălin Ristea, Andrei Anghel, Radu Tudor Ionescu

Moreover, considering the lack of databases for this task, we release as open source a large scale data set that closely replicates real world automotive scenarios for single-interference cases, allowing others to objectively compare their future work in this domain.
