Signal Processing for Near-Field Radar - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240295629 titled 'Signal Processing for Near-Field Radar
The patent application relates to near-field radar filters that can improve measurements near a radar unit on a vehicle.
- The filter is designed to counteract the near-field effects of radar reflection signals received at the radar unit.
- It takes into account the azimuth angle and distance of surfaces in the environment causing the radar reflection signals.
- The filter is used to determine the azimuth angle and distance for surfaces causing a second set of radar reflection signals.
- The vehicle's control system can use this information to adjust based on the surfaces causing the radar reflection signals.
Potential Applications: - Autonomous driving systems - Collision avoidance systems - Traffic monitoring and management
Problems Solved: - Improving accuracy of radar measurements in near-field conditions - Enhancing the performance of radar systems in complex environments
Benefits: - Increased safety on the road - More reliable radar data for decision-making - Enhanced efficiency of radar systems
Commercial Applications: Title: Advanced Radar Filters for Autonomous Vehicles This technology can be utilized by automotive companies developing self-driving cars to enhance the performance of radar systems for better navigation and safety features.
Questions about Near-Field Radar Filters: 1. How do near-field radar filters improve the accuracy of radar measurements?
- Near-field radar filters compensate for the effects of radar reflection signals received at close distances, providing more precise data for analysis.
2. What are the key factors considered by the filter in determining the azimuth angle and distance for surfaces causing radar reflection signals?
- The filter takes into account the azimuth angle and distance of surfaces in the environment to accurately identify the sources of radar reflection signals.
Original Abstract Submitted
examples relate to near-field radar filters that can enhance measurements near a radar unit. an example may involve receiving a first set of radar reflection signals at a radar unit coupled to a vehicle and determining a filter configured to offset near-field effects of radar reflection signals received at the radar unit. in some instances, the filter depends on an azimuth angle and a distance for surfaces in the environment causing the first set of radar reflection signals. the example may also involve receiving, at the radar unit, a second set of radar reflection signals and determining, using the filter, an azimuth angle and a distance for surfaces in the environment causing the second set of radar reflection signals. the vehicle may be controlled based in part on the azimuth angle and the distance for the surfaces causing the second plurality of radar reflection signals.
