In a device for measuring angular positions by using radar pulses and mutually overlapping beam characteristics of at least two antenna elements, a switchable phase shifter is provided in the signal path of at least one antenna element which is switchable in the time-division multiplexing between different phase states. The replacement distance is determined from the target distance D by means of a correction function, and the correction function is determined exclusively from non-ballistic characteristic values and at least as a function of the target distance D and the difference in angle between the elevation angle \u03b1 and the shooting angle. Another mechanism for holding flies is carried within said housing. The fruit is uniformly large in size, somewhat acidic in flavor, globose in shape, clingstone in type, very firm in texture, yellow in flesh color, and almost full red in skin color. A second vacuum-activated probe is configured to successively remove individual seeds from the seed-alignment trough and to plant each removed seed in a selected planting chamber.
