Abstract
A near object detection (NOD) system includes a plurality of sensors, each of the sensors for providing detection coverage in a predetermined coverage zone and each of the sensors including a transmit antenna for transmitting a first RF signal, a receive antenna for receiving a second RF signal and means for sharing information between each of the plurality of sensors in the NOD system.
Claims15
A near object detection system adapted to be coupled to a vehicle having a plurality of vehicle systems, the near object detection system comprising:
- a plurality of sensors, each of said plurality of sensors for providing data associated with a range cell in one of a plurality of predetermined coverage zones;
- a processor, coupled to receive and process the range cell data from one or more of said plurality of sensors, said processor adapted to provide a processor output signal to one or more of the plurality of vehicle systems, wherein said processor includes a target tracker portion adapted to maintain track information from a plurality of targets with the track information being generated from the range cell data provided by the one or more of said plurality of sensors;
- and
- means, coupled to each of said plurality of sensors and to said processor, for sharing information between at least some of said plurality of sensors.
A near object detection system for a vehicle, comprising:
- a plurality of sensors disposed about a perimeter of the vehicle, each of said plurality of sensors providing data associated with a range cell in a respective one of a plurality of predetermined coverage zones about the perimeter of the vehicle;
- and
- wherein each of said plurality of sensors has a respective predetermined range, angular extent, and velocity range based upon respective coverage zone requirements;
- and
- a processor, coupled to one or more of plurality of sensors, said processor adapted to receive and process the range cell data provided thereto from the one or more of said plurality of sensors, said processor including a target tracker portion adapted to maintain track information from a plurality of targets with the track information being generated from the range cell data.
A near object detection system, comprising:
- a plurality of sensors, each of said plurality of sensors for providing detection coverage in a respective one of a plurality of predetermined coverage zones;
- a multiple hypothesis tracker for processing data from each of said plurality of sensors to make a hypothesis about data association, resolution, and data quality;
- a prediction filter coupled to said multiple hypothesis tracker for scheduling the plurality of sensors;
- a public track former, coupled to said plurality of sensors, for generating data to control operation of said plurality of sensors;
- an estimator/best state vector subsystem coupled to said public track former;
- and
- a vehicle control crash management interface coupled to said estimator/best state vector subsystem and to said public track former.
