Abstract
An apparatus for emitting electromagnetic radiation and receiving partial radiation reflected by objects, and determines the instantaneous performance of its system detection. The apparatus includes a device for emitting a frequency-modulated transmit signal that has at least two signal sequences which have ramps, each succeeding one another in the frequency characteristic, with gaps in between, the signal sequences being interleaved with each other with a predetermined time offset so that in each case a first ramp of each of the signal sequences is output before a second ramp of one of the at least two signal sequences is output. The apparatus includes a mixer, an analog-to-digital converter, a transform device, and a device for detecting phase noise. The phase changes of the receive signals are compared over all two-dimensional spectra to a precalculated model, and the cause of the phase noise is ascertained with the aid of predetermined criteria.
