Method and arrangement for the radar monitoring with disclosed matic fmcw - radar

摘要

The present invention relates to a process as well as a radar arrangement for the radar monitoring with disclosed matic fmcw - radar. In the method, in the receiving unit with at least one first receiving antenna on objects in a region to be monitored reflected signal transmitted by the transmitting unit as a monitoring signal receiving. In a first process variant, with a further receiving antenna without reflection objects a control signal transmitted by the transmitting unit as a signal is received directly. In a second variant, in the receiver unit, a simulation of the transmission signal of the transmitting unit as a replica - signal is generated. The directly signal or replica - signal is then mixed in a manner similar to that in each case with the monitoring signal, in order to obtain a mixing signal. The mixing signal is to obtain the desired radar information evaluated. The method and the associated radar arrangement permit a radar monitoring with a high dynamic range at a low sampling rate.
