Bats-inspired frequency hopping for mitigation of interference between automotive radars

It was reported for specific bats, that they use a certain scheme to shift the frequencies of their echo location calls to counteract interferences with conspecifics. As in road traffic, an increasing number of cars is equipped with radar sensors, there is also the problem of mutual interference. The available frequency bands are limited, so a randomized frequency hopping will not be the best solution. In this paper, we adapt the frequency hopping behavior of the bats reported in [1] to a radar system. We discuss the algorithm and show measurements of its performance in an anechoic chamber.
