Abstract
A built-in self-test, BIST, radar unit () is described. The BIST radar unit () comprises: a frequency generation circuit () configured to generate a mmW transmit signal; a transmitter circuit comprising: at least one phase shifter () configured apply at least one phase shift to the mmW transmit signal; and at least one phase inverter () coupled to the at least one phase shifter () and configured to invert a phase of the phase shifted mmW transmit signal. A receiver configured to receive and process a received version of the mmW transmit signal. The at least one phase inverter () is configured to rotate the phase shifted mmW transmit signal to apply a secondary modulation to the mmW transmit signal; and the receiver is configured to receive and process a received version of the mmW transmit signal to determine an operational state of the BIST radar unit () based on a determined phase shift performance of the secondary modulation of the received version of the mmW transmit signal.
