An object's distance is determined using either two RF transmitters and an RF receiver, or a two RF receivers and an RF transmitter. When using two RF transmitters, the direction of the first transmitter is changed until it reaches a first direction defined by a first angle at which the power of the RF signal—transmitted by the first transmitter—reflected off the object and received by the receiver reaches a maximum value. The direction of the second transmitter is also changed until it reaches a second direction defined by a second angle at which the power of the second RF signal—transmitted by the second transmitter—reflected off the object and received by the receiver reaches a maximum value. The distance between the object and the first transmitter is defined by the distance between the two transmitters, the second angle, and the difference between the first and second angles.
