Fig. 6

The instantaneous ground diffraction pattern at 2 MHz for a partial reflection height of 80 km. The scale of the diffraction pattern is indicated by the overlay of the BPMF large array. The basic antenna spacing is 91.4 m. For this work, the small transmitting array at the bottom right of the figure was used for transmission. The image of the diffraction pattern is taken from movies produced by Briggs and Holmes (1973) and Holmes (1975) and described by Briggs (1993). Videos of the movies are included as additional material with this paper
