A Three-station Lightning Detection System available in PDF, EPUB and Kindle. A three-station network is described which senses magnetic and electric fields of lightning. Directional and distance information derived from the data are used to redundantly determine lightning position. This redundancy is used to correct consistent propagation errors. A comparison is made of the relative accuracy of VLF direction finders with a newer method to determine distance to and location of lightning by the ratio of magnetic-to-electric field as observed at 400 Hz. It was found that VLF direction finders can determine lightning positions with only one-half the accuracy of the method that uses the ratio of magnetic-to-electric field.

Download and read online ebook Development of Single Station Lightning Detection System write by Mohd Azrin Mohd Arif Fadzillah. This book was released on 2012. Development of Single Station Lightning Detection System available in PDF, EPUB and Kindle. The lightning strikes billion of times, kill many of people, and damages billion of assets per year. This problem may be properly managed by using a lightning detection system. In this project, the lightning detector circuit was designed by using PIC16F877A microcontroller. The purposes of this project are to determine the distance and direction of lightning strikes. One wire antenna and apair of loop antenna were attached to the circuit. A pair of loop antennas is used to sense the magnetic field produce by the lightning strike and a wire antenna is used to sense the electric field produce by the lightning strike. Three variable resistor will act as the antenna in this project to give the variety input to the PIC microcontroller. CCS compiler is a software used to write the program to microcontroller. The program written for Graphic User Interface (GUI) is done by using Microsoft Visual Basic 6.0. LED will blink and LCD will display the data of distance and direction of lightning strike. Meanwhile, GUI will display the results also with the add on of electric field and magnetic field values of each antenna and saveall the data in a laptop.

This book was released on 2018-07-06. Development of Algorithms and Error Analyses for the Short Baseline Lightning Detection and Ranging System available in PDF, EPUB and Kindle. NASA, at the John F. Kennedy Space Center (KSC), developed and operates a unique high-precision lightning location system to provide lightning-related weather warnings. These warnings are used to stop lightning- sensitive operations such as space vehicle launches and ground operations where equipment and personnel are at risk. The data is provided to the Range Weather Operations (45th Weather Squadron, U.S. Air Force) where it is used with other meteorological data to issue weather advisories and warnings for Cape Canaveral Air Station and KSC operations. This system, called Lightning Detection and Ranging (LDAR), provides users with a graphical display in three dimensions of 66 megahertz radio frequency events generated by lightning processes. The locations of these events provide a sound basis for the prediction of lightning hazards. This document provides the basis for the design approach and data analysis for a system of radio frequency receivers to provide azimuth and elevation data for lightning pulses detected simultaneously by the LDAR system. The intent is for this direction-finding system to correct and augment the data provided by LDAR and, thereby, increase the rate of valid data and to correct or discard any invalid data. This document develops the necessary equations and algorithms, identifies sources of systematic errors and means to correct them, and analyzes the algorithms for random error. This data analysis approach is not found in the existing literature and was developed to facilitate the operation of this Short Baseline LDAR (SBLDAR). These algorithms may also be useful for other direction-finding systems using radio pulses or ultrasonic pulse data. Starr, Stanley O. Kennedy Space Center...
