Weather Radar Vertical Profile View Target Value Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weather radar systems require frequent adjustments of the vertical profile view direction due to the motion of both the aircraft and weather, leading to erratic displays and increased pilot workload.
Innovation Solution
A method and system that automatically adjusts the target value for generating a vertical profile view based on the motion of the aircraft and weather, using processing electronics to calculate and update the target value in real-time, ensuring accurate and consistent display of weather data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pilot manually selects a direction for generating a vertical profile view, then the initial display accuracy is improved, but the display becomes erratic and requires frequent adjustments due to aircraft and weather motion
Solution Approach 1:
The system automatically adjusts the target value for vertical profile views by calculating aircraft motion and weather motion itself, without requiring continuous pilot intervention. The processing electronics compute adjusted target values based on detected motion parameters, enabling the system to self-correct and maintain accurate displays autonomously
Solution Approach 2:
The system uses feedback from aircraft motion data and weather motion data to continuously update the target value. By monitoring how the aircraft and weather move over time, the system adjusts the vertical profile direction dynamically to maintain correlation with the area of focus, eliminating erratic displays
2Device complexity
If the vertical profile view direction is fixed after initial selection, then device complexity is reduced, but the display loses correlation with the area of focus due to motion
Solution Approach 1:
The system transitions from a static fixed direction approach to a dynamic adjustment approach. The target value for vertical profile views is continuously updated based on real-time aircraft motion and weather motion data, allowing the display to adapt and maintain correlation with the area of focus as conditions change
Solution Approach 2:
The system pre-calculates adjusted target values by anticipating aircraft and weather motion. Rather than reacting to loss of correlation, the system proactively adjusts the vertical profile direction based on detected motion trends, maintaining display accuracy before significant drift occurs

AI summary
A system and method for adjusting a target value for generating a vertical profile view in an aircraft weather radar system is provided. Processing electronics are configured to receive a target value for generating a vertical profile view of weather detected by the radar system. The processing electronics are also configured to adjust the target value to account for the motion of the aircraft and/or the motion of the detected weather.
