ABSTRACT:
A storm monitoring apparatus and method is described wherein two H-field antennas are oriented with respect to the heading axis of an aircraft or the like at an angle of 45.degree.. The signals developed by these two antennas are picked-up by small R-F transformers which serve the inherent function of integrating the signals and extracting the H-field current component. A printed circuit board structuring of the two antennas provides for consistency of fabrication and reliability as well as compactness. The monitoring apparatus exhibits broad band frequency response to evaluate lightning strike rate to determine storm range and intensity. A computer control test utilizing diagnostic coils at the antenna carries out periodic testing of the performance of the device and a component such as a gravity switch provides an indication to the control system as to the orientation of mounting of the antenna on an aircraft. The outputs of the antennas are digitized and evaluated at a high rate and range information is developed from these digitized data in consequence of the transfer function of the atmosphere. For example, range is developed by an analysis of the decay of various frequency components emanating from a lightning burst. Select memory retention of the data is continuously provided such that the operator can look to immediately preceding storm evaluations to determine whether the condition in which flight is being made is one into worsening or improving weather.
