16. A millimeter-wave radar module testing system comprising:
a millimeter-wave radar module comprising a millimeter-wave radar sensor; and
a controller coupled to the millimeter-wave radar sensor, the controller configured to:
perform a plurality of tests indicative of a performance level of the millimeter-wave radar module;
compare respective results from the plurality of tests with corresponding test limits; and
generate a flag when a result from a test of the plurality of test is outside the corresponding test limits, wherein performing the plurality of tests comprises:
transmitting a signal with a transmitting antenna coupled to the millimeter-wave radar sensor,
modulating the transmitted signal with a test signal, and
capturing first data from a first receiving antenna using an analog-to-digital converter of the millimeter-wave radar sensor, wherein generating the flag comprises generating the flag based on the captured first data.
