RECEIVER DEVICE, MULTI-FREQUENCY RADAR SYSTEM AND VEHICLE

摘要

A receiver device for a radar system comprises a receive antenna module arranged to simultaneously receive a plurality of radar signals; a mixer module connected to the antenna module and arranged to simultaneously convert the plurality of radar signals into a plurality of intermediate frequency signals, each of the plurality of intermediate frequency signals having a frequency that is comprised in a different corresponding one of a plurality of intermediate frequency ranges; and a wideband analog-to-digital-converter module connected to the mixer module, arranged to simultaneously convert the plurality of intermediate frequency signals into a digital representation, and having a bandwidth comprising a plurality of non-overlapping bandwidth portions, wherein each of the plurality of intermediate frequency ranges is comprised in a different one of the non-overlapping bandwidth portions.
