A novel method of mitigating the mutual interference between multiple LFMCW radars for automotive applications

Linear frequency modulated continuous wave (LFMCW) radar has been proven to be a highly reliable sensor to improve traffic safety. However, the increased use of LFMCW radars creates new challenges in mutual interference for automotive applications. In this contribution, an efficient approach is developed to reduce mutual interference by applying randomized sub-band spectra technique. Compared with state-of-the-art methods, the proposal shows superior performances.
