Use of a mobile smart device for initiating an operation based on an enhanced characteristic of an object while the mobile smart device is within an interior of a vehicle, the mobile smart device comprising: a radar system comprising: one or more antennas; at least one transceiver coupled to the antennas and configured to: transmit, via one or more of the antennas, radar transmit signals (306, 402); and receive, via one or more of the antennas, radar reflection signals (304; 410, 412, 414); at least one processor; and at least one computer-readable storage media comprising processor-executable instructions that, responsive to execution by the processor, cause the mobile smart device to: transmit, via the radar system and while the mobile smart device is within the interior of the vehicle, one or more radar transmit signals (306, 402); receive, via the radar system: an internal radar reflection signal (410, 412) caused by a reflection of one of the radar transmit signals off a portion of the vehicle; and an external radar reflection signal having penetrated a windshield of the vehicle and caused by a reflection of one of the radar transmit signals off the object that is not the portion of the vehicle, another portion of the vehicle, or an occupant within the vehicle; estimate a position of the mobile smart device relative to the vehicle based on the internal radar reflection signal (410, 412); analyze the external radar reflection signal to determine a characteristic of the object; determine, based on the estimated position of the mobile smart device relative to the vehicle and the characteristic of the object, the enhanced characteristic of the object; and initiate the operation based on the enhanced characteristic of the object. a radar system comprising: one or more antennas;
