Abstract
Methods and apparatus for a phase array radar to generate fan beams with curve of constant phase with spoiling in u and/or v space. In embodiments, beam pattern weighting is phase-only and applicable to transmit and receive. In embodiments, the beam pattern accounts for the apparent curvature of the horizon in uv space.
Claims21
A method, comprising:
- generating a beam from a phased array radar face having a curve of constant phase,
- wherein the beam is spoiled in u space,
- wherein the beam is spoiled in v space, and
- wherein the beam has a pattern that is flat in real space and curved in uv space that follows the horizon.
1 more element
A phased array radar system, comprising:
- a beamformer and a beam spoiler module configured to:
- generate a beam from a face of the phased array radar system having a curve of constant phase;
- a plurality of phase shifters connected to the beamformer;
- and
- a plurality of antennas connected to the plurality of phase shifters, respectively,
- wherein the beam is spoiled in u space,
- wherein the beam is spoiled in v space, and
- wherein the beam has a pattern that is flat in real space and curved in uv space that follows the horizon.
5 more elements
An article, comprising:
- a non-transitory computer-readable medium having stored instructions that cause a phase array radar to generate a beam from a face of the phased array radar having a curve of constant phase,
- wherein the beam is spoiled in u space,
- wherein the beam is spoiled in v space, and
- wherein the beam has a pattern that is flat in real space and curved in uv space that follows the horizon.
