Abstract

A method of sensing a target in a target detection system is provided. The method comprises processing circuitry, a multiplexer coupled to the processing circuitry and to a plurality NT of transmit antennas forming a sparse transmit uniform linear array, ULA, the multiplexer being configured to generate multiplexed and phase modulated transmit signals based on signals from a local oscillator, theprocessing circuitry being further coupled for receiving signals via a plurality of receive antennas forming a dense receive ULA. The method comprises transmitting the plurality of transmit signals via the transmit antennas so as to form a general radiation pattern corresponding to a block circulant probing signal matrix and receiving via the receive antennas receive signals resulting from backscattering of the plurality of transmit signals transmitted towards K targets. The method further comprises processing the received reflection signals to determine the presence, range and / or angular position of a target within a field of view of the transmit antennas. A corresponding target detection system and a vehicle incorporating the target detection system are also disclosed.

Description

technical field [0001] The present invention relates generally to object detection using multiple-input multiple-output (MIMO) radars such as those used in automotive applications, and more particularly to a method for transmit MIMO adaptive beamforming using block-cycle decomposition of cross-correlation matrices A method and system for object detection. Background technique [0002] In order to obtain the maximum amount of information about the scene around the vehicle (e.g., through multiple-input multiple-output (MIMO)), future automotive radar systems will communicate with several devices (transceiver device) to operate together. In order to be able to handle different signals, a form of orthogonality of the different codes transmitted by the transceiver is necessary. This can be done eg by switching certain devices on and off (time division multiplexing). [0003] In the following, previous publications ("references") listed at the end of this document are cited wit...
