Radar Transmission Adaptation for Wireless Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radar systems face interference and inaccurate target detection due to congestion from multiple radar signals operating independently in a wireless communication environment, leading to false target detection and reduced accuracy.
Innovation Solution
Radar devices adjust transmission parameters based on congestion levels by reducing maximum detection range, decreasing transmit power, and prioritizing detection of closer objects when interference exceeds a threshold, thereby minimizing interference to other devices.

Engineering Contradiction Analysis
1Measurement precision
If radar devices operate independently with full transmission power and maximum detection range, then each device can detect distant objects, but interference increases and detection accuracy decreases in congested environments
Solution Approach 1:
The radar system dynamically adjusts its transmission parameters including maximum detection range and transmit power based on real-time congestion level detection. When congestion is detected, the system reduces these parameters to minimize interference; when congestion decreases, parameters are restored to improve detection capability.
Solution Approach 2:
The system changes key operational parameters (maximum detection range, transmit power) in response to detected congestion levels. This allows the radar to adapt its performance characteristics to environmental conditions, reducing interference during high congestion while maintaining detection accuracy when conditions permit.
2Object-affected harmful factors
If radar devices reduce maximum detection range and transmit power in congested environments, then interference to other devices decreases, but detection capability for distant objects is reduced
Solution Approach 1:
The system dynamically adjusts operational parameters based on real-time congestion assessment. By continuously monitoring the environment and adapting transmission power and detection range, the system maintains optimal detection capability while minimizing interference to and from other radar devices.
Solution Approach 2:
The radar system implements feedback mechanisms where detection results and congestion levels are used to adjust subsequent transmission parameters. This closed-loop control ensures that detection capability is maintained at appropriate levels while interference is reduced when necessary.
3Measurement precision
If radar systems prioritize detection of closer objects in congested environments, then detection accuracy for nearby targets improves, but coverage area is reduced
Solution Approach 1:
The radar system applies local quality by prioritizing detection resources and accuracy for closer objects in congested environments. By focusing energy and processing on nearby targets where detection is most critical, the system maintains high accuracy for immediate surroundings while accepting reduced coverage for distant areas.

AI summary
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for adapting a radar transmission based on a congestion level. A wireless device, such as a radar device, a UE, a base station, a vehicle, etc., may detect a congestion level of a wireless communication environment that includes the wireless device. The wireless device may have at least one of a first FOV or a first range within the wireless communication environment. The wireless device may transmit, based on the congestion level exceeding a threshold, a radar signal that corresponds to the wireless device having at least one of a second FOV or a second range in the wireless communication environment that is smaller than the at least one of the first FOV or the first range.
