There is provided a system for non-contact computation of an indication of at least one of a fall and a near-fall of a target individual based on ultrasound transmission, comprising: ultrasound transceiver(s) for generating an ultrasound transmission and receiving a reflection of the ultrasound transmission and a non-transitory memory having stored thereon a code for execution by hardware processor(s) of a computing device in communication with the ultrasound transceiver(s), the code comprising: code for activating the ultrasound transceiver(s) for generating the ultrasound transmission, and for receiving the reflection of the ultrasound transmission code for performing a spectrogram analysis of the received reflection of the ultrasound transmission to compute features and code for computing an indication of at least one of: a fall of a target individual, and a near-fall of the target individual, by a statistical classifier classifying the features.
