Method for operating several FMCW radar sensors in a radar network or multistatic radar, and a radar sensor designed for this

摘要

In a method for operating multiple radar sensors in a radar network, the transmitted FMCW radar signals are each preceded by a CW signal that contains binary-coded information about transmission parameters of the transmitting radar sensor and / or other information. In a preferred embodiment, each radar sensor receives corresponding CW signals with information about transmission parameters of other radar sensors in the radar network, processes the information and, if a match is detected, adjusts its own transmission parameters so that they no longer match the transmission parameters of the other radar sensors. The method enables the trouble-free operation of several radar sensors in a radar network and can also be used with a multistatic radar.
