Method for Reducing Mutual Interference in Radars
Patent application, 2019

A distributed FMCW radar communication system for interference mitigation in an ego unit comprising at least one RadCom unit arranged for radar sensing in a radar mode and for data communication in a communication mode with at least one target unit switching between the radar mode and the communication mode in time and using separate frequency bands for the radar mode and the communication mode, using a random medium access technique for communication, where the ego unit comprises a plurality of RadCom units and a control unit adapted to control the plurality of RadCom units to use different starting times and frequency bands based on at least one received control message by means of communication during a radar frame duration received by means of the data communication, where the starting times of different FMCW radars are separated sufficiently so as they are orthogonal.
