Solution Overview
Problem
In radar systems used for monitoring airport runways and highways, when one radar device fails, there is a disruption in monitoring the affected area until the failed device is replaced, which can be challenging and time-consuming due to operational difficulties on these areas.
Innovation Solution
A radar system configuration where each radar device normally monitors its area using a first modulation band, and when a device fails, adjacent radar devices switch to a narrower second modulation band to expand their monitoring area and cover the failed device's zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radar device fails and is replaced, then the monitoring function is restored, but the replacement operation is time-consuming and disrupts continuous monitoring
Solution Approach 1:
The patent implements preliminary action by pre-configuring spare radar devices in standby positions adjacent to active radar devices. When a radar device fails, the adjacent spare device is already in position and can immediately switch to the failed device's monitoring area, eliminating the need for time-consuming replacement operations. This pre-positioning of backup resources ensures continuous monitoring without interruption.
Solution Approach 2:
The patent applies parameter changes by dynamically switching the modulation band of the radar signal when a radar device fails. The adjacent spare radar device changes its operating parameters (modulation band) to match the failed device's parameters, enabling it to effectively take over the failed device's monitoring area. This parameter switching allows seamless transition and maintains monitoring continuity.
2Measurement precision
If each radar device monitors its own area with a wide modulation band, then detection precision is high, but when a device fails, the monitoring area cannot be covered
Solution Approach 1:
The patent implements universality by designing radar devices with multi-functional capability. Each radar device can perform both its primary monitoring function and a backup function. When a radar device fails, the adjacent spare device can universally perform the failed device's monitoring function by switching to the same modulation band and monitoring area, making the system more adaptable and versatile.
Solution Approach 2:
The patent applies dynamics by making the radar system's monitoring configuration dynamic rather than static. The modulation band and monitoring area of each radar device can dynamically change based on system needs. When a device fails, the adjacent spare device dynamically switches its parameters to cover the failed area, ensuring continuous and adaptable monitoring coverage.

Function Achieved in This Case
This configuration allows for continuous monitoring of the area even when a radar device fails, enabling the system to operate uninterrupted until the failed device is restored, thus enhancing safety and reducing operational costs.
Implementation Method 1
a radar system that detect an object existing in a monitoring area using a radar device
Implementation Method 2
When an object T (reflecting object) exists in a detection area of the radar device 100, the radar transmission wave is reflected by the object T

AI summary
In this example, a radar system is such that normally, each of a plurality of radar devices 100-1 to 100-6 monitors the monitoring area for the same using a radar signal that has been frequency modulated within a first modulation band, and when one of the plurality of radar devices 100-1 to 100-6 fails, at least one radar device (for example, radar device 100-1) adjacent to the radar device (for example, radar device 100-2) that has failed monitors the monitoring area of the radar device that has failed using a radar signal that has been frequency modulated within a second modulation band that is narrower than the first modulation band. As a result, even if one of the radar devices fails, it is possible to continue monitoring the monitoring area of the radar device.
