Abstract
A vehicle system includes a signal processing module and a first antenna that provides a first transmitted signal that has a first phase. A second antenna of the system provides a second transmitted signal that has a second phase that differs from the first phase. At least one receive antenna of the vehicle system receives first and second received signals that correspond to the first and second transmitted signals, respectively. The signal processing module processes the received first and second signals based on the first and second transmitted signals and selectively controls transmissions of the first and second transmitted signals.
