In order to refine a device and a method for registering, detecting, and/or analyzing
at least one object, a registration range and/or at a detection gate being displaced
at a scanning speed over a measuring range, in such a way that a target-unique
velocity measurement is ensured in continuous detection operation with low latency
time and resistance to fluctuations, it is provided that, the receive circuit be
divided into at least two channels, which are operable separately from one another,
in particular using at least one power divider unit connected downstream from the
output terminal of the I/Q mixing unit, of which the first channel of the receive
circuit is designed for the purpose of displacing the registration range and/or
the detection gate at a constant scanning speed over the entire measuring range,
and the second channel of the receive circuit is designed for the purpose of displacing
the registration range and/or the detection gate at a variable, in particular reducible
scanning speed over the measuring range and/or setting the registration range and/or
the detection gate at a predefinable position within the measuring range for a
predefinable period of time at a negligible scanning speed.
