Abstract
A system comprising includes a plurality of three dimensional line-scanner LIDAR sensors disposed to provide a set of fanned beams that travel from one horizon into the air to the other horizon arranged to provide a light fence to detect an object that breaks the light fence and a sensor processor connected to the plurality of three dimensional multi-beam line-scanner LIDAR sensors to establish a vector of travel and a velocity of the object that passes through the multi-beam light fence at the location of where the beams are broken.
Claims18
A system comprising:
- a plurality of three dimensional line-scanner LIDAR sensors disposed to provide a set of fanned beams that travel from one horizon into the air to the other horizon arranged to provide a light fence to detect an object that breaks the light fence;
- and
- a sensor processor connected to the plurality of three dimensional multi-beam line-scanner LIDAR sensors to establish a vector of travel and a velocity of the object that passes through the multi-beam light fence at the location of where the beams are broken wherein the plurality of three dimensional line-scanner LIDAR sensors are arranged along a line to provide the light fence along the line and networked together.
A method comprising:
- providing a set of fanned beams that travel from one horizon into the air to the other horizon arranged to provide a light fence to detect an object that breaks the light fence;
- and
- providing a vector of travel and a velocity of the object that passes through the light fence at the location of where the beams are broken wherein the plurality of three dimensional line-scanner LIDAR sensors are arranged along a line to provide the light fence along the line and networked together.
A detection system for detecting drones comprising:
- a plurality of three dimensional line-scanner LIDAR sensors disposed to provide a set of fanned beams that travel from one horizon into the air to the other horizon arranged to provide a light fence to detect an object that breaks the light fence and provide an inbound vector wherein the plurality of three dimensional line-scanner LIDAR sensors are arranged along a line to provide the light fence along the line and networked together;
- and
- a long range sensor, in response to the inbound vector, to acquire and track the object detected by at least one of the plurality of three dimensional line-scanner LIDAR sensors.
