Abstract
A radar system having multiple layers and a radiating array of elements, wherein signals are presented to the elements as they propagate through a slotted wave guide.
Claims20
A radiating structure, comprising:
- a plurality of slotted transmission lines, comprising:
- a plurality of boundary lines defining each transmission line, wherein slots are positioned along a length of each transmission line;
- and
- a plurality of irises positioned proximate each of the slots, wherein the plurality of irises are equally spaced along the length of each transmission line;
- and
- an array of radiating elements proximate the slotted transmission lines adapted to receive a transmission signal from the slotted transmission lines and generate a radiation pattern corresponding to the transmission signal.
3 more elements
A radar system, comprising:
- a radiating array structure comprising a plurality of radiating elements;
- a reactance control means to change a behavior of the radiating array structure;
- and
- a transmission array structure coupled to the radiating array structure and feeding a transmission signal through to the radiating array structure, the transmission array structure comprising:
- a plurality of super element transmission paths, each having a plurality of vias forming transmission paths and a plurality of slots feeding the transmission signal to the radiating array structure.
2 more elements
A radar system, comprising:
- a radiating array of elements;
- a slotted waveguide positioned proximate the radiating array of elements, wherein the slotted waveguide comprises a plurality of slots and a plurality of irises interleaved with the plurality of slots along a lengthwise direction of the slotted waveguide;
- an antenna control circuit adapted to control phases of signals to the radiating array of elements to achieve radiation beam directivity;
- and
- an artificial intelligence engine coupled to the antenna control circuit.
