Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems struggle to create both horizontal and vertical weather scans for any location in front of an aircraft efficiently while maintaining effective antenna utilization.
Innovation Solution
A radar system performs multiple horizontal scans to identify cells, derives a first vertical profile, and uses this data to create a second vertical profile, which is refined and applied to proximal weather, combining data to generate a high-resolution vertical scan at any location using interpolation or extrapolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple horizontal scans are performed to create vertical weather scans at any location, then the versatility and coverage of weather data is improved, but the antenna utilization efficiency and system complexity worsen
Solution Approach 1:
The patent divides the weather data into discrete cells, where each cell contains vertical profile information. This segmentation allows the system to process and transmit weather data in manageable units, enabling versatile weather scan coverage without overwhelming system complexity. The cell-based architecture allows selective processing of only relevant weather cells rather than processing entire volumetric datasets.
Solution Approach 2:
The patent transforms traditional 2D horizontal radar scans into 3D vertical profiles by adding the elevation dimension. Through interpolation between horizontal scan planes, the system creates vertical weather information without requiring physical vertical antenna movement, thus achieving enhanced weather coverage versatility while avoiding the complexity of mechanical vertical scanning systems.
2Measurement precision
If vertical scans are conducted along specific headings using antenna movement, then measurement precision is improved, but the loss of time and productivity worsen
Solution Approach 1:
The patent performs preliminary horizontal scans to capture weather data at multiple elevation planes before generating vertical profiles. By pre-collecting the necessary horizontal scan data across different elevations, the system eliminates the need for time-consuming antenna movements during vertical profile generation, thus maintaining measurement precision while significantly reducing scan time.
Solution Approach 2:
Instead of physically moving the antenna to conduct vertical scans, the system creates virtual copies of weather data through interpolation algorithms. These computational copies reconstruct vertical profiles from horizontal scan data, achieving the same measurement precision as physical vertical scans but without the time penalty of antenna movement.
3Manufacturing precision
If high-resolution vertical profiles are generated for all cells, then the manufacturing precision and data quality improve, but the quantity of data and transmission requirements worsen
Solution Approach 1:
The patent applies different levels of vertical profile processing to different weather cells based on their significance. High-resolution vertical profiles are generated only for cells containing weather phenomena of interest, while other cells receive lower-resolution or no vertical processing. This local quality approach maintains high data quality where needed while dramatically reducing overall data volume and transmission requirements.

AI summary
A radar system performs a plurality of horizontal scans; from the horizontal scans, the radar system identifies several cells. Based on the horizontal scans, the radar system produces a first vertical profile that is applied to the identified cells. The radar system performs one or more vertical scans of one of the identified cells to get measured reflectivity values in elevation. The measured reflectivity values are used to create a second vertical profile. The second vertical profile is used to refine the first vertical profile at the location of the identified cell and also to proximal weather. The data used to create the first and second vertical profiles can be combined into a data packet and stored within the radar or transmitted to a remote device. The remote device can reproduce a third vertical profile from the information in the data packet at any point.
