Zusammenfassung
One common problem of frequency modulated
continuous wave radar is leakage from the transmitter to the
receiver. The leakage power is orders of magnitude larger than
the target return power and appears as a very strong signal in
the first few range bins. Additionally, the residual phase noise
density of the local oscillator occurs around the leakage signal,
which often raises the noise floor and limits the dynamic range of
a radar system at the close proximity of the sensor. In this paper
a novel system concept that cancels the phase noise around the
dominating leakage path is proposed, mathematically derived,
and proven by radar measurements with a radar demonstrator
at 77 GHz.
