Claim:
A method of calibrating a plurality of radars, the plurality of radars for use together in a radar system, the method of calibrating the plurality of radars comprising: selecting a reference radar from among the plurality of radars; selecting one or more pairs of radars, each one of the pairs of radars including the reference radar and a respective paired radar from among the plurality of radars; generating calibration values associated with the reference radar and with the paired radar; generating initialization values associated with the reference radar and with the paired radar; transmitting an adjusted signal with the paired radar and an unadjusted signal with the reference radar, the adjusted signal generated in accordance with the initialization values and the calibration values; receiving a first composite signal with the reference radar and a second composite signal with the paired radar, the first and second composite signals associated with the adjusted signal and the unadjusted signal; and coherently summing the first composite signal and the second composite signal to provide a final signal.
