Abstract
Method and system of calibrating and cohering at least one radar antenna in receive (RX) mode and transmit (TX) mode, comprising performing RX mode calibration on at least one radar antenna using radio frequency (RF) far field calibration source, determining RF phase Øusing RF far field calibration source for each at least one radar antenna, operating at least one radar antenna in RX mode with at least one near field antenna to determine plurality of RX mode phases in at least one radar antenna and at least one near field antenna, operating at least one radar antenna in TX mode with at least one near field antenna to determine plurality of TX mode phases in at least one radar antenna and at least one near field antenna, and deriving TX mode calibration phases as function of determined RX mode phases and determined TX mode calibration phases.
