Abstract

In this paper the passive methods of detection and measuring distance to a source of lightning discharge are considered. A new method is presented and correspondent algorithms of signal processing are developed for measuring the distance between the aircraft and a source of lightning. The function of devices that can be designed on the basis of the method consists in timely detection of a lightning threat in order to provide the pilot with necessary information to avoid dangerous zones during the flight. This is especially important under the condition of new CNSiATM concept and 'free flight' policy when a pilot has much more freedom for decision making. The method uses the orthogonal (on polarization) components of electromagnetic field generated by lightning as measurable values. Limitations of the method are analyzed and comparison with other methods is done. Advantages and peculiarities of new method are shown. The method can be implemented as a device for small aircraft instead of weather radar. Other using of proposed method is application together with airborne weather radar on the basis of data fusion and displaying resulting information.
