There is provided a radar sensor and method. The radar sensor comprises a plurality of transmit and receive antennas, a transceiver, a digital signal processor, a filter and an interface. The transceiver is configured to digitize received radar signals to provide a plurality of digital samples. The digital signal processor is configured to form a measurement matrix by transforming the plurality of digital samples into a distance/relative velocity matrix for each combination of the transmit and receive antennas. The filter is configured to identify samples forming the measurement matrix having a signal to noise ratio higher than a threshold value. The interface is configured to transmit the identified samples and their location in the measurement matrix to a remote host processor configured to further carry out direction of arrival processing on the identified samples.
