Abstract
The present invention relates to radar systems and associated methods of operation. In one aspect, the present invention relates to an automotive radar system including at least one receiver configured to receive radar signals, a processing system configured to receive from at least one receiver, a received radar signal, process the received radar signal to generate a data frame that has dimensions of M rows by M columns of elements from a covariance matrix, determine a rank N of the data frame. The system is further configured to set all elements in a first subset of columns numbered N through M of the data frame to zero values to create a padded data frame, calculate a pseudo-inverse value of the padded data frame, determine a direction of arrival of at least one target using the pseudo-inverse value, and control an operation of a vehicle using the direction of arrival.
