Antenna configurations for reduced radar complexity
First Claim
1. A transmit and receiving system comprising,a first array including a first plurality of antenna elements disposed to provide a transmit antenna adapted to provide a plurality of transmit beams each having a transmit pattern shape;
- a second array including a second different plurality of antenna element disposed to provide a receive antenna adapted to provide a plurality of receive beams each having a receive pattern shape;
a beam switching system coupled to the first array being operative to selectively form a plurality of transmit beams; and
a beam combining system coupled to the second array and being operative to selectively form at least one transmit beam; and
a beam combining system coupled to the second array and being operative to selectively form a plurality of receive beams wherein the beam switching system and beam combining system are operative such that different combinations of transmit and receive beam pattern shapes can be used to provide a plurality of different two-way antenna patterns.

Abstract
A transmit and receiving system including a first array including a first plurality of antenna elements disposed to provide a transmit antenna. The system further includes a second array having a second different plurality of antenna elements disposed to provide a receive antenna. The first array is coupled to a first switching system, which is operative to selectively form at least one transmit beam. The second array is coupled to a beam combining system, which is operative to selectively form a plurality of receive beams.
