摘要： An apparatus is provided, comprising processing circuitry configured to determine a harmonic spectrum of an intermediate frequency, IF, signal of a radar sensor, determine an undesired signal component of the IF signal caused by at least one of a crosstalk of the radar sensor and a near-range obstacle in a field of view of the radar sensor based on the harmonic spectrum, and determine a calibrated signal having a reduced contribution from the undesired signal component based on the undesired signal component and the IF signal.

摘要： An apparatus is provided comprising processing circuitry configured to process data indicating a receive signal of a sensor through isolating a locally stationary signal component of the receive signal from at least one of a stochastic and a deterministic signal component of the receive signal.
