1Speed
If dual- and multi-Doppler techniques are used for velocity estimation in overlapping radar networks, then real-time velocity measurement capability is improved, but measurement fidelity and accuracy deteriorate
Solution Approach 1:
The patent segments the velocity estimation process into multiple independent processor components, each handling specific aspects of the measurement. This allows different processing strategies to be applied to different data streams, balancing real-time capability with measurement fidelity by dividing the complex estimation task into manageable segments that can be processed concurrently with appropriate accuracy controls.
Solution Approach 2:
The system dynamically adjusts processing parameters and resource allocation based on changing weather conditions and user priorities. The velocity processors can adapt their computational intensity and measurement strategies in real-time, allowing the system to optimize between speed and accuracy depending on the operational context and available network resources.
2Area of stationary object
If a large number of radar nodes are deployed to improve spatial density and coverage, then network coverage and spatial resolution are improved, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent implements universal velocity processors that can handle multiple functions and data types from different radar nodes. These processors are designed to work with various scan parameters and configurations, providing a standardized interface that simplifies the integration of additional nodes while maintaining system manageability despite increased network scale.
Solution Approach 2:
The velocity processors act as intermediary components between the distributed radar nodes and the central control system. They perform local processing and data fusion, reducing the complexity burden on the central system by handling velocity estimation tasks distributed across the network, thus managing system complexity while enabling expanded coverage.
3Measurement precision
If more network resources are allocated to improve measurement accuracy, then vector velocity and variance measurement accuracy are improved, but resource utilization efficiency and response time to changing conditions deteriorate
Solution Approach 1:
The system changes processing parameters dynamically based on user priorities and weather conditions. The velocity processors can adjust their computational parameters, such as averaging windows and filtering intensity, to optimize the balance between measurement accuracy and response time. This allows the system to maintain high accuracy when resources permit while responding quickly when conditions change rapidly.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor measurement quality and resource utilization in real-time. Based on this feedback, the velocity processors can adjust their operational parameters to maintain optimal accuracy while managing resource consumption. This feedback loop ensures that accuracy improvements do not come at the permanent cost of reduced response capability.
