The present disclosure provides a circuitry for radar detection data disambiguation for a mobile platform. The circuitry is configured to obtain radar detection data from a radar sensor mounted on the mobile platform, wherein the radar detection data indicate, for each of a plurality of targets, a radial velocity and an angle of arrival; estimate, based on the radar detection data, an ego-motion of the mobile platform; and determine an unambiguous radial velocity value of a target of the plurality of targets based on the ego-motion and the radar detection data.

Circuitry and method

A radar system which can be used in a vehicle is presented. The radar system has a radar sensor for transmitting and receiving first radar signals and an evaluation device for processing radar signals received by the radar sensor. The radar system also has at least one active radar tag which is configured to retransmit received radar signals, amplified and modulated, as second radar signals, and the evaluation device is configured to determine information about an object both on the basis of components, received by the radar sensor, of the first radar signals reflected at the object and on the basis of components, received by the radar sensor, of the second radar signals reflected at the object.

Coherent, multi-static radar system, in particular for use in a vehicle

A circuitry for simultaneous localization and mapping for a mobile platform, wherein the circuitry is configured to:

An OFDM radar sensor system having a plurality of transmitting and receiving units. One of the transmitting and receiving units is an OFDM radar sensor, and another of the transmitting and receiving units is a repeater which is configured to modulate a signal generated and transmitted by the OFDM radar sensor and received by the repeater into a signal orthogonal to the signal received by the repeater and to emit the modulated signal. The OFDM radar sensor is configured to separate a portion of a signal received by the OFDM radar sensor, which portion corresponds to the modulated signal, from a monostatic portion of the signal received by the OFDM radar sensor.
