Abstract

The simplicity and cost factor of millimeter-wave hardware restrict the implementation of near-field radar imaging systems in many applications. These drawbacks are exacerbated when using multiple antennas, each being connected to a dedicated sampling chain. To significantly alleviate these constraints, the use of analog multiplexing techniques appears inevitable. The choice of a suitable solution for a given application can be challenging. Among the available technologies, this study focuses on frequency beamsteering and space-frequency random scanning, comparing the characteristics and performances of these techniques in a radar imaging scenario in the 92-96GHz frequency band.
