	%X In recent years, the presence of short-range
millimeter-wave radar in civil application has increased significantly.
Autonomous driving, security, 3D imaging and high data rate
communication systems are a few examples. The next challenge is
the integration inside small form-factor devices, such as smartphones
(e.g. gesture recognition). The main challenge is implementation of
a truly low-power, low-complexity high-resolution radar. The most
popular approach is the Frequency Modulated Continuous Wave
(FMCW) radar, with an analog multiplication front-end. In this
paper, we present an approach for adaptive estimation and correction
of impairments of such front-end, specifically implemented using
the Six-Port Device (SPD) as the multiplier element. The proposed
algorithm was simulated and implemented on a 60 GHz radar lab
prototype.
