MULTIPLE TRANSMISSION METHODS FOR IMPROVING THE OPERATION OF AUTOMOTIVE RADAR SYSTEMS

摘要

Methods for disambiguating the location of a radar contact using an N×M dimensioned radar array are provided. In the horizontal plane, the method comprises transmitting a first radar energy pattern in a direction, collecting reflected energy of the first radar energy pattern from the contact, transmitting a second radar energy pattern in the direction and collecting reflected energy of the second radar energy pattern from the contact. The method further comprises comparing the collected energy of the first radar energy pattern and the collected energy of the second radar energy pattern and determining if the contact is located in a side lobe or a main lobe of the first and second radar energy pattern based on the comparison. In the vertical plane, other similar embodiments may be used to determine if the radar antenna(s) are blocked by an obstacle.

1. A method for disambiguating a location of a radar contact comprising:
transmitting a first radar energy pattern in a specified; 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.
