Claim Text:
1. A method for disambiguating a location of a radar contact comprising: transmitting a first radar energy pattern in a specified direction; collecting reflected energy of the first radar energy pattern from the radar contact; transmitting a second radar energy pattern in the specified direction; collecting reflected energy of the second radar energy pattern from the radar contact; comparing the collected reflected energy of the first radar energy pattern and the collected reflected energy of the second radar energy pattern; and determining if the radar contact is located in a side lobe or the main lobe of the first and second radar energy pattern based on the comparison; wherein a first matrix of antenna elements is used to transmit the first radar energy pattern and a second matrix of antenna elements is used to transmit the second radar energy pattern, the first matrix is of a different size that the second matrix; and wherein the first matrix is determined not to be blocked when the collected reflected energy of the second radar energy pattern is greater than the collected reflected energy of the first radar energy pattern and the collected reflected energy of the second radar energy pattern is greater than a predetermined threshold.
