Novel fully electronic active real-time millimeter-wave imaging system based on a planar multistatic sparse array

Summary form only given, as follows. The interest on active millimeter-wave imaging systems is increasing nowadays due to their utilization in security, medical, and industrial applications. Multistatic arrays offer the chance for high reduction factors in the number of antennas, and allow for fully electronic solutions. A new array architecture is presented that is suitable for real-time operation and delivers high image quality. An example array is demonstrated for operation from 72 to 80 GHz, along with results on imaging of humans.
