“…The exploitation of CW Doppler radars has been suggested in several application contexts. In healthcare, for instance, they are often referred to as "bioradars" and can be employed to detect sleep apneas (Alekhin et al, 2013;Baboli et al, 2015) or mental stress (Fernàndez and Anishchenko, 2018) in humans, and breathing disorders in living animals (Anishchenko et al, 2015). Moreover, the application of CW bioradars has been suggested also for preventing the sudden infant death syndrome (Li et al, 2009), tumor tracking in radiation therapy (Li and Lin, 2014), and cardiac motion imaging (Wang et al, 2013).…”
