Target testing based on raw uncalibrated radar data

A method comprising:

• receiving uncalibrated raw channel responses from a sensor comprising a multiple-input multiple-output (MIMO) antenna array;
• generating, based on the uncalibrated raw channel responses, an uncalibrated raw MIMO measurement matrix;
• extracting singular values from the MIMO measurement matrix;
• determining, based on the singular values, a quantity of dominant singular values;
• evaluating, based on the quantity of dominant singular values, whether the channel responses are valid;
• and
• responsive to the channel responses being valid, passing the sensor to be used in a real-world application.

A non-transitory computer-readable medium comprising instruction that, when executed cause a processor to:

• receive uncalibrated raw channel responses from a sensor comprising a multiple-input multiple-output (MIMO) antenna array;
• generate, based on the uncalibrated raw channel responses, an uncalibrated raw MIMO measurement matrix;
• extract singular values from the MIMO measurement matrix;
• determine, based on the singular values, a quantity of dominant singular values;
• evaluate, based on the quantity of dominant singular values, whether the channel responses are valid;
• responsive to the channel responses being valid, pass the sensor to be used in a real-world application;
• and
• responsive to the channel responses being invalid, determine a mitigation that leads to a validation of the channel responses such that the sensor can be used for a real-world application.
