Multiple radar combining for increased range, radar sensitivity and angle accuracy
First Claim
1. A method of radar processing comprising:
- radiating a first signal beam from an antenna of a first radar in the direction of a target;
radiating a second signal beam from an antenna of a second radar in the direction of the target;
receiving echo signals from the first signal beam at the first and second radars;
receiving echo signals from the second signal beam at the first and second radars;
processing the echo signals received at the first radar to produce first radar processed echo signals;
processing the echo signals received at the second radar to produce second radar processed echo signals; and
combining the first and second radar processed echo signal values to form an aggregate value.

Abstract
A mechanism for combining signals of multiple radars to achieve increased range, radar sensitivity and angle accuracy is provided. A first signal beam is radiated from an antenna of a first radar in the direction of a target. A second signal beam is radiated from an antenna of a second radar in the direction of the same target. The echo signals from the first signal beam and the second signal beam are received at both radars. The echo signals received at the first radar are processed to produce first radar processed echo signals and the echoes signals received at the second radar are processed to produce second radar processed echo signals. The first and second radar processed echo signals are combined to form an aggregate value.

12. A method of processing radar signals comprising:
-
radiating a first signal beam by a first radar with the first signal beam being radiated in the direction of a target; receiving, in the first radar, echo signals from the first signal beam; receiving, in the first radar, echo signals from a second signal beam radiated by a second different radar radiating the second signal beam in the direction of the target, the first radar and the second radar being spaced a predetermined distance apart; and processing, in the first radar, the echo signals from the first and second signal beams to provide first-radar processed echo signals. - View Dependent Claims (13)

14. A radar comprising:
-
a transmitter which provide signals to and antenna to radiate a first signal in the direction of a target; a receiver to receive echo signals from the first signal beam and echo signals from a second signal beam radiated in the direction of the target by a second antenna of a second radar; and circuitry to process the echo signals from the first and second signal beams received by the receiver, and to combine the processed echo signals with echo signals from the first and second signal beams that have been received by a receiver of the second radar and processed, to form an aggregate value. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
