RADAR SYSTEM, RADAR DEVICE, AND INTERFERENCE AVOIDANCE METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18276884 titled 'RADAR SYSTEM, RADAR DEVICE, AND INTERFERENCE AVOIDANCE METHOD

Simplified Explanation

The patent application describes a radar system that can effectively utilize frequency in the presence of interference, even with three or more radar devices. The system includes a schedule management controller that predicts interference time periods, determines interference avoidance measures, and assigns different frequencies to radar devices to avoid interference.

• Radar system with three or more radar devices
• Schedule management controller predicts interference time periods
• First interference avoidance measure assigns different frequencies to radar devices during predicted interference time periods
• Second interference avoidance measure for radar devices unable to avoid interference with the first measure

Potential Applications

The technology can be applied in military radar systems, air traffic control radar systems, weather monitoring radar systems, and autonomous vehicle radar systems.

Problems Solved

1. Interference between radar devices 2. Efficient frequency utilization in the presence of interference

Benefits

1. Improved radar system performance 2. Enhanced accuracy of radar data 3. Increased reliability of radar operations

Potential Commercial Applications

Optimized Radar Frequency Utilization in Multi-Device Systems

Possible Prior Art

There may be prior art related to radar interference avoidance techniques in multi-device systems, but specific examples are not provided in the patent application.

How does the schedule management controller predict interference time periods?

The patent application does not detail the specific algorithms or methods used by the schedule management controller to predict interference time periods. Further information on the predictive models or techniques employed would provide a clearer understanding of the system's operation.

What are the specific restrictions on the number of frequency channels that the radar devices must adhere to?

The patent application mentions keeping a restriction on the number of frequency channels while assigning different frequencies to radar devices during interference time periods. More information on the limitations or constraints imposed on the frequency channels would help in understanding the system's design and operation better.

Original Abstract Submitted

A radar system, a radar device, and an interference avoidance method are obtained that can utilize frequency effectively even in three or more radar devices. A radar system includes three or more radar devices and a schedule management controller. Schedule management controller predicts an interference time period that is a time period during which the overlapping scanning/radiation range is generated, determines a first interference avoidance measure that is a measure to cause radar devices to use respective different use frequencies while keeping a restriction on the number of frequency channels, in the predicted interference time period, and determines a second interference avoidance measure to be performed by a radar device that is unable to avoid interference by the first interference avoidance measure.
