AI Technical Summary

Technical Problem

In existing methods for observing severe convective weather, the lack of information from single data sources, insufficient risk assessment dimensions, and uneven scheduling and resource allocation for multi-target tasks lead to insufficient timeliness and accuracy in early identification, waste of resources, or missing measurements of key targets, affecting observation efficiency and effectiveness.

Method used

By fusing multi-source data, using satellite cloud images, radar data, and underlying surface data, a sensitive target evaluation function is constructed to identify potential targets, track their lifecycles, and assess risks. This dynamically optimizes radar scanning methods and achieves optimal resource allocation.

Benefits of technology

It improves the timeliness of observation and the reliability of early warning for severe convective weather, dynamically monitors key targets, balances the allocation of radar resources, avoids resource waste, and enhances disaster prevention and mitigation capabilities.

Abstract

Embodiments of the present disclosure provide a method and system for satellite-ground radar cooperative observation based on sensitive targets, which are applied to the technical field of weather radar. The method comprises the following steps: acquiring satellite, radar and underlying surface data; identifying and processing the radar data to obtain the number, position, area of potential targets and the early warning level corresponding to each potential target, and comprehensively obtaining the satellite-ground joint early warning level; using the underlying surface data, potential targets and the satellite-ground joint early warning level to construct a sensitive target evaluation function and calculate the sensitivity score; and arranging and combining the sensitive targets and radar scanning modes, and performing optimization processing to select the optimal scanning mode. In this way, real-time tracking and dynamic monitoring of strong convective weather can be achieved, guiding multiple weather radars to efficiently carry out cooperative operation and improving the observation timeliness and early warning reliability of high-disaster strong convective weather.
