A system and corresponding method are described, for use in alerting on objects in path of vehicle's propagation. The system comprising RF transmission/reception unit comprising at least one phased array antenna unit, and a control unit. The RF transmission/reception unit is configured for periodically scanning a selected region by transmission of interrogating RF signal and collecting reflected RF signals from the selected region and generate based thereon pattern data indicative of the collected RF signal, and for transmitting the pattern data to the control unit. The control unit is configured and operable for processing the pattern data for determining existence of interfering object in path of propagation of a vehicle carrying the system, and for generating alert data indicative of existence of one or more interfering objects.
