Mountain fire monitoring and positioning method based on small-sized radar

Abstract

The invention discloses a mountain fire monitoring and positioning method based on a small-sized radar. According to the mountain fire monitoring and positioning method based on the small-sized radar, the Doppler radar is used for performing stereoscopic scanning within an appointed region, a suspected fire point meeting the mountain fire echo feature can be found by analyzing the basic reflectivity and the radial speed; the fire point is confirmed according to a result of an infrared sensor, so that mountain fire monitoring and positioning for a power transmission line are realized. The mountain fire monitoring and positioning method based on the small-sized radar well solves the problem that the Doppler radar cannot effectively distinguish fire echo and precipitation echo with low intensity during fire condition monitoring and the problem that the infrared sensor is relatively low in space resolution by combining a Doppler radar stereoscopic scanning result and an infrared sensor result.

Description

technical field [0001] The invention relates to a method for monitoring and locating a mountain fire, in particular to a method for monitoring and locating a mountain fire based on a small radar. Background technique [0002] As we all know, forest fires will cause many difficulties and inconveniences to human production and life. Since ancient times, fire has brought serious disasters to human society with its huge destructive power. The power system is an important pillar for the development of the national economy of human society. The transmission lines used to transmit electric energy are widely distributed and often need to pass through complex mountain forests. The unique climate and topographical characteristics of the mountain forests are easy to cause wildfires. According to relevant information, the direct losses and indirect impacts caused by wildfires are huge. The applicant found in the research on wildfire monitoring of power system transmission lines that a...

AI Technical Summary

Problems solved by technology

Its main shortcoming is that the mountain fire monitoring satellite is affected by the transit time and cannot realize real-time monitoring of mountain fires. The spatial resolution of satellite remote sensing technology is low. For example, the spatial resolution of the channel used to identify fire spots in MODIS is 1km. The monitoring results are greatly affected by weather and environmental factors. If there is cloud cover, the satellite infrared channel can only monitor the temperature on the upper surface of the cloud cover.
