Interference Mitigation Evaluation Methodology for Automotive Radar

Interference mitigation is crucial to restore the degraded detection performance of interfered radars. For developing advanced interference mitigation methods, a well-defined evaluation methodology is required to assess the performance of different methods thoroughly and appropriately. In this paper, we propose to evaluate interference mitigation methods by measuring detection performance and signal-to-noise ratio in the range-Doppler domain. We especially suggest measuring the performance analytically without involving any detector but based on the estimated probability density functions of the target and background to isolate the effect of the detector in the performance evaluation. The time-domain thresholding and time-frequency domain thresholding methods are compared to validate the proposed methodology on simulated data.
